17th Congress of the International Commission for Optics: Optics for Science and New Technology, 1996 Quantum theory is vital for the next generation data processing devices. As computers become faster they must become smaller because of the finiteness of the speed of light. The history of computer technology has involved a sequence of changes from one type of physical realisation to another - from gears to relays to valves to transistors to integrated

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 ...

Defects in Quantum Computers [PDF]
Scientific Reports, 2018 AbstractThe shift of interest from general purpose quantum computers to adiabatic quantum computing or quantum annealing calls for a broadly applicable and easy to implement test to assess how quantum or adiabatic is a specific hardware. Here we propose such a test based on an exactly solvable many body system–the quantum Ising chain in transverse ...

Universality in quantum computation [PDF]
Proceedings of the Royal Society of London. Series A: Mathematical and Physical Sciences, 1995 We show that in quantum computation almost every gate that operates on two or more bits is a universal gate. We discuss various physical considerations bearing on the proper definition of universality for computational components such as logic gates.

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.

Towards Post-Quantum Blockchain: A Review on Blockchain Cryptography Resistant to Quantum Computing Attacks [PDF]
IEEE Access, 2020 Blockchain and other Distributed Ledger Technologies (DLTs) have evolved significantly in the last years and their use has been suggested for numerous applications due to their ability to provide transparency, redundancy and accountability.
