Photon-Number-Resolving Detection for Viable Gottesman-Kitaev-Preskill State Preparation

Miller Eaton, Rajveer Nehra, Olivier Pfister

Abstract

We include photon-number-resolving detection in “photon catalysis” and apply it to generating non-Gaussian quantum states, including perfectly displaced single-photon states, high-fidelity squeezed cat and Gottesman-Kitaev-Preskill states.

Generating Gottesman-Kitaev-Preskill Qubits Over Continuous-Variable Cluster States with Photon-Number-Resolving Measurements

Miller Eaton, Carlos González-Arciniegas, Rafael N. Alexander +2 more

We develop a method to embed Schrödinger Cat states in continuous-variable cluster states with high probability using photon-number-resolving detection. Embedded cat states can then be bred into Gottesman-Kitaev-Preskill qubits with Gaussian measurements on the cluster.

All-Optical Gottesman-Kitaev-Preskill Qubit Generation via Approximate Squeezed Coherent State Superposition Breeding

Andrew J. Pizzimenti, Daniel Soh

We demonstrate that by breeding approximate squeezed coherent state superpositions, Gottesman-Kitaev-Preskill qubits can be generated all-optically with success probabilities two orders of magnitude greater than photon number resolving measurement based methods.

Non-Gaussian and Gottesman–Kitaev–Preskill state preparation by photon catalysis

Miller Eaton, Rajveer Nehra, Olivier Pfister

Abstract Continuous-variable quantum-computing is the most scalable implementation of QC to date but requires non-Gaussian resources to allow exponential speedup and quantum correction, using error encoding such as Gottesman–Kitaev–Preskill (GKP) states. However, GKP state generation is still an experimental challenge. We show theoretically that photon catalysis, the interference of coherent states with single-photon states followed by photon-number-resolved detection, is a powerful enabler for non-Gaussian quantum state engineering such as exactly displaced single-photon states and M -symmetric superpositions of squeezed vacuum (SSV), including squeezed cat states ( M = 2). By including photon-counting based state breeding, we demonstrate the potential to enlarge SSV states and produce GKP states.

A unified optical platform for non-Gaussian and fault-tolerant Gottesman-Kitaev-Preskill states

Ozlem Erkilic, Aritra Das, Biveen Shajilal +3 more

Quantum technologies, encompassing communication, computation, and metrology, rely on the generation and control of non-Gaussian states of light. These states enable secure quantum communication, fault-tolerant quantum computation, and precision sensing beyond classical limits, yet their practical realisation remains a major challenge due to reliance on high-photon-number Fock states or strong non-linearities. Here we introduce a unified optical framework that removes this constraint, using only Gaussian inputs, optical parametric amplification, and heralded photon detection. Within a single architecture, we demonstrate the generation of photon-added squeezed states with near unit fidelity, cubic-phase-like states with strong non-linearities and fidelities above 98.5%, and squeezed-cat states exceeding 99% fidelity that can be iteratively bred into GKP grid states surpassing the 9.75 dB fault-tolerance threshold. Operating entirely below 3 dB of input squeezing, the approach provides a scalable, experimentally accessible platform that unites the state resources required for quantum communication, metrology, and computation within one coherent optical framework.
