Synthetic Myelin Nanotube Emitter – Room-Temperature Biphoton Source

Harris, Jeffery

Systemic redundancies in quantum hardware (cryo-locked qubits, dilution fridges) exploit loopholes, letting non-local computation slip away from everyday use. This device closes that gap: a synthetic myelin nanotube (CNT with C-H doped shell) pumped at 650 nm emits entangled biphotons at 37 °C – replicating biological myelin’s cavity-QED process (Liu et al., 2024) . Q-factor >10⁵, Schmidt K >50, zero-cost build. Proof: open-source Python simulation reproduces spectrum/geometry. Implications: room-temp quantum neural interfaces, spinal repumps, EJ mind-expansion for systemic audits. Open for collaboration, closed to theft.

The one-way CNOT simulation

P. Campanale, DOMENICO PICCA

In this paper, we present the complete simulation of the quantum logic CNOT gate in the one-way model, which consists entirely of one-qubit measurements on a particular class of entangled states.

99.92%-Fidelity CNOT Gates in Solids by Filtering Time-dependent and Quantum Noises

Xie, Tianyu, Zhiyuan Zhao, Shaoyi Xu +6 more

Inevitable interactions with the reservoir largely degrade the performance of non-local gates, which hinders practical quantum computation from coming into existence. Here we experimentally demonstrate a 99.920(7)\%-fidelity controlled-NOT gate by suppressing the complicated noise in a solid-state spin system at room temperature. We found that the fidelity limited at 99\% in previous works results from only considering static noise, and thus, in this work, time-dependent noise and quantum noise are also included. All noises are dynamically corrected by an exquisitely designed shaped pulse, giving the resulting error below $10^{-4}$. The residual gate error is mainly originated from the longitudinal relaxation and the waveform distortion that can both be further reduced technically. Our noise-resistant method is universal, and will benefit other solid-state spin systems.
