Quantum Computing: Summary Basic Mechanism: Parallel computation along all possible computational paths, with selective manipulation of probability amplitudes Main Features: Problem instances encoded as states of a quantum system (e.g. spins of n electrons, polarization values of n photons etc.) The s...
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...

The purpose of our work is to show that, in the near future, Quantum Computing algorithms may solve many currently intractable financial problems, and render obdoi:10.2139/ssrn.2694133Marcos Lopez de PradoSocial Science Electronic Publishing
Scaling up quantum computers to attain substantial speedups over classical computing requires fault tolerance. Conventionally, protocols for fault-tolerant quantum computation demand excessive space overheads by using many physical qubits for each logica
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-...

we get as a consequence of Theorem 1 an explicit formula for the reconstruction map that circumvents the need to solve an exponential-sized linear system. Our next proposition makes this explicit. For clarity of presentation, the detailed proofs of all the results in this subsection are provided...
Quantum Computers The fundamental difference about all this is: At any given time: n bits can be in one of the 2^n states. n qubits can be in up to 2^n states simultaneously. Suggests an incredible potential in parallel computing power. ...
