Squeezing-Enhanced Photon-Number Measurements for GKP State Generation, pre-print Nov 2025

We present a simple architecture relying on Gaussian resources and measurements for generating high-quality GKP states within a time-multiplexed cluster state. By using squeezing as a control mechanism, combined with fewer homodyne steps, dynamic resetting, and an improved breeding algorithm, the scheme reduces noise and achieves an 11.5 dB fault-tolerance squeezing threshold under the RHG surface code, without photon-number resource states or active switching.

End-to-end switchless architecture for fault-tolerant photonic quantum computing, Quantum 9, 1796 (2025)

We present an end-to-end architecture for fault-tolerant continuous variable (CV) quantum computation using only passive on-chip components that can produce photonic qubits above the fault tolerance threshold with probabilities above 90% and encodes logical qubits using physical qubits sampled from a distribution around the fault tolerance threshold. 

Random alloy AlInAsSb single photon avalanche diodes with high breakdown probability, J. Appl. Phys. 137, 153102 (2025)

In this work, the avalanche triggering probability of ∼1 μm thick Al0.79InAsSb multiplier grown on InP is measured. Avalanche probability values as large as 85% were attained at room temperature for an over-bias of 8%, confirming the capacity of antimonide-based multipliers to achieve high photon detection efficiencies.

Generation of squeezed quantum microcombs with silicon nitride integrated photonic circuits, Optica 10, 1100-1101 (2023)

A two-mode squeezed microresonator-based frequency comb is demonstrated with CMOS-compatible silicon nitride integrated photonic circuits.
