Simultaneous Execution of Quantum Circuits on Current and Near-Future NISQ Systems
IEEE Transactions on Quantum Engineering, 2022 In the noisy intermediate-scale quantum (NISQ) era, the idea of quantum multiprogramming, running multiple quantum circuits (QCs) simultaneously on the same hardware, helps to improve the throughput of quantum computation.

Laser annealing heals radiation damage in avalanche photodiodes
EPJ Quantum Technology, 2017 Avalanche photodiodes (APDs) are a practical option for space-based quantum communications requiring single-photon detection. However, radiation damage to APDs significantly increases their dark count rates and thus reduces their useful lifetimes in ...

A (quasi-)polynomial time heuristic algorithm for synthesizing T-depth optimal circuits
npj Quantum Information, 2022 We investigate the problem of synthesizing T-depth optimal quantum circuits for exactly implementable unitaries over the Clifford+T gate set. We construct a subset, $${{\mathbb{V}}}_{n}$$ V n , of T-depth 1 unitaries.
