BPI/BITS Quantum Risk Calculator The Bank Policy Institute (BPI) BITS membership has been organizing response efforts regarding the quantum computing risk to cryptography issue since 2015. The “Quantum Risk Calculator” referenced below was recently released to the BPI/BITS membership to raise awarenes...
Quantum Computing: Problems and Future Directions Decoherence: Environmental noise may inadvertently “measure” the system, thereby disturbing the computation (current decoherence time ~ 1 ms) Software solution: Error correcting codes may help ([Shor et al.]) Scaling: All physical implementations so f...

The scalability, error correction and practical problem solving are important challenges for quantum computing (QC) as more emphasized by quantum supremacy (QS) experiments. Quantum path computing (QPC), recently introduced for linear optic based QCs as an unconventional design, targets to obtain scala...
To a great extent, this progress was stimulated by an interplay between the quantum communication theory and quantum information ideas related to more recent development in quantum computing. This new age of quantum information science is characterized by emphasis on the new possibilities (rather than...
time-independent coefficients, thus quantum simulations can be done without using the cumbersome Dyson’s series and time-ordering operators. Our formulation allows both qubit and qumode (continuous-variable) formulations, and thei...
Diamond is important to quantum information because it sits at the interface between solid-state and optical implementations of quantum computing. As indicated above, the color centers of diamond are the only solid-state photostable room-temperature single photon emitters known, and no other solid-...
