Volume I argued that post-quantum cryptography (PQC / PPQC) is a change of locks, and that the archive will fork into physical and biological media by 2030–2035. This second volume treats the immediate layer: what is already operationally true in late August 2026 for technology, for the financial system, and for private capital. Immediacy here is not a claim that a cryptographically relevant quantum computer exists. It is the claim that harvest-now-decrypt-later collection is live; that Mosca's inequality is already failed for long-lived financial and family records; that vendor, HSM and FIPS gates in 2026–2027 will decide who can transact with serious counterparties; and that private equity and family offices are allocating as if quantum were either a listed lottery ticket or a distant IT project — both errors. The note maps the technology that can be bought this year, the financial-system doctrine now issued by the G7, BIS, U.S. Treasury, HKMA, FINMA, Taiwan FSC and RBI, and a barbell allocation for PE and family businesses that separates defensive crypto-agility spend from speculative compute exposure.

LinkedIn cluster circulating in late August 2026, anchored by Keith King's warning that quantum computing will force a fundamental reset of cybersecurity, restates the now-standard post-quantum cryptography (PQC / PPQC) programme: harvest-now-decrypt-later (HNDL) risk, inventory, crypto-agility, and migration to NIST FIPS 203–205 primitives. That programme is correct and late. It is also incomplete. Quantum security will not be exhausted by quantum-resistant mathematics, nor even by quantum key distribution. Once a cryptographically relevant quantum computer is treated as a planning fact rather than a distant research object, information seeks other bodies. This note contrasts the PQC reset with leading theories — Mosca's inequality, QKD and quantum networks, hardware isolation, cryptographic provenance, molecular archival science, and living-neuron computation — and argues that the archive itself will fork into physical, chemical and biological media. Data centres will cease to be a single architectural species. Cyberpunk conditions of the Neuromancer type, especially curbed rather than total wars over access to infrastructure, are treated as operationally plausible from 2027 and as a structural feature of livelihood by 2030–2035. The author's earlier perpetual-horizon and near-dated Q-Day line (c. August 2027 as a forcing date) is retained as a governance tempo, not as a hardware prophecy.

K SC This paper provides a detailed conceptual and market assessment of the strategic impetuses driving enterprise and institutional investment in quantum computing, as crystallised in recent analyses of corporate preparedness programmes (including the Wall Street Journal reporting synthesised by King, 2026). It examines the offensive (optimisation, simulation, analytics) and defensive (post-quantum cryptography, cryptographic inventory, harvest-now-decrypt-later risk) rationales for early capital allocation under conditions of radical timeline uncertainty. Drawing on 2025–2026 capital-market data, the paper maps private-equity and public-market repercussions: record venture funding, concentration in late-stage rounds, multi-billion-dollar valuations of pure-play platforms, and the opening of exit windows via conventional IPOs and SPACs. It then develops an epistemic and ontological reading of market signalling, arguing that capital markets function as distributed knowledge institutions that price optionality under dual computational and cryptographic futures. Markers of market maturation are presented alongside an assessment of the hypothesis that meaningful quantum capability—and associated 'transcendence' effects—may begin to materialise from 2027.

K SC As the second quantum revolution transitions from laboratory demonstration to early commercial and strategic deployment, private equity (PE) firms are recalibrating their investment theses. Drawing on the technical foundations (Volumes I and V), ontological shifts (Volume II), governance frameworks (Volumes III and V), multipolar trajectories, and Base-ofthe-Pyramid survival imperatives (Volume VI), this seventh volume analyses the emerging strategies of private equity in the quantum domain. It identifies the specific areas attracting capital, the risk-mitigation approaches being adopted, and the evolving nature of financing across two critical time horizons: the next 18–36 months (2026–2028) and the subsequent period through 2031. The analysis concludes that while pure-play quantum computing remains high-risk, the most attractive opportunities lie in quantum-AI convergence platforms, postquantum cryptography migration, quantum sensing applications, and enabling infrastructure. Financing is expected to shift from predominantly venture and growth equity toward larger, more structured vehicles including dedicated quantum infrastructure funds and strategic coinvestments with sovereign and corporate actors.

Quantum computing threatens the security foundations of global financial systems, exposing long-lived data and signed digital assets to “harvest-now, decrypt-later” attacks. While the timeline for cryptographically relevant quantum computers remains uncertain, regulatory signals from the USA, UK, EU, Canada, and Australia converge: financial institutions and payment infrastructures must begin migrating to post-quantum cryptography (PQC) now to preserve confidentiality, integrity, and systemic stability. This paper maps emerging standards and roadmaps, contrasting binding requirements like the EU’s DORA crypto-agility provisions with non-binding guidance from NIST, ENISA, and ETSI. Despite a shared intent to secure high-risk use cases by 2030–2031 and complete migration by 2035, divergences in enforcement and milestones create uncertainty for cross-border banks and financial market infrastructures. In parallel, technical adoption is advancing: major browsers, cryptographic libraries (OpenSSL/BoringSSL), and CDNs (e.g., AWS CloudFront) have deployed hybrid PQC key exchange in TLS 1.3, proving confidentiality defenses are viable at internet scale. The paper synthesizes historical transition lessons, sector-specific regulatory drivers, and operational constraints in payment infrastructures to derive a new, principle-based migration: crypto-agility, risk-prioritized scoping, hybrid deployment, vendor and supply-chain alignment, independent testing, and proactive supervisory engagement. Acting now reduces long-tail exposure and ensures readiness for imminent compliance and interoperability deadlines.
Abstract: This study develops a unified approach to quantum-safe security in accounting and finance by linking concept analysis, a design framework, and implementation guidance to measurable risk reduction. Concept analysis distinguishes confidentiality lifetimes, “harvest-now-decrypt-later” exposure, and cryptographic dependence across ledgers, payments, reporting pipelines, and audit trails. Building on this, a layered framework is articulated comprising (i) threat taxonomy and impact surfaces for financial workflows; (ii) standards alignment with post-quantum cryptography (PQC) suites and crypto-agility policies; (iii) key- and certificate-lifecycle orchestration using HSM-backed services; and (iv) controls for ledger integrity, non-repudiation, and regulatory evidence. The core problem addressed is the absence of end-to-end, standards-compatible designs that deliver quantum resilience without disrupting performance, interoperability, or compliance. Methodology integrates formal threat modeling, standards mapping, and reference-architecture synthesis with scenario evaluation in representative financial processes (inter-system reconciliation, e-signature workflows, and archival protection). Results show that phased PQC migration with automated key rotation and dual-stack validation reduces exposure windows, preserves auditability, and maintains throughput within target bounds for typical batch and near-real-time workloads. Impact arises from procurement-ready patterns, crypto-agile runbooks, and assurance artifacts that support regulatory review and external audit. The implications include actionable migration roadmaps for institutions, improved durability of financial records against future cryptanalytic advances, and clearer accountability through evidence bundles that connect controls to quantifiable risk reduction. Keywords: quantum-safe cryptography, post-quantum cryptography (PQC), financial systems security, accounting information systems, harvest-now decrypt-later, crypto-agility, key management and HSM, digital signatures and non-repudiation, ledger integrity, regulatory compliance, audit evidence, zero-trust architecture, certificate lifecycle, risk assessment and migration planning
This volume fact-checks and reviews claims that quantum computers are beginning to show practical scientific value (exemplified by Keith King's LinkedIn assessments and concurrent IBM-associated results), provides a concise review of the core mechanics of quantum computation, situates current progress against the prior investigative thread (Jurczak's 2026 Perpetual Five-Year Technologies framework, the anatomical review of that paper, and the full chapter-wise reassessment of the 2021 treatise Blockchains: Gaming and Collusion), enumerates pros and cons, compares major prediction regimes, and directly addresses the question of Q-Day. The user's hypothesis that Q-Day arrives in August 2027 is examined against hardware roadmaps, logical-qubit counts, error-correction overheads and cryptographic thresholds. The central finding is that scientific utility for selected, hybrid, verification-constrained problems is emerging in 2025–2026, consistent with an early phase of technical individuation, while cryptographically relevant quantum computers (CRQCs) capable of breaking widely deployed public-key cryptography remain most probably in the early-to-mid 2030s, with accelerated estimates clustering around 2029–2032 and August 2027 lying outside credible current trajectories.
