So, by asking a single “quantum question” you can discover instantly whether the Oracle always has the same opinion about the numbers 0-7, or has differing opinions. Normally, you’d be stuck asking as many as 5 ordinary questions. The same technique continues to work even for very large...

Well, just like the sport athletic gear puts it out: impossibility is nothing. Quantum computing is possible, and its acceptance in all cadres of the industry will simplify the work process since its technology leverages the superpositioning of qubits to sample multiple scenarios at the same time...
Quantum computing operates on the quantum principles of superposition and entanglement. Whereas classical computers calculate with transistors representing either 1 or 0, quantum machines use qubits, which can represent both simultaneously. This lets them perform calculations in minutes thatwould take classic...
It thus seems natural to use the same majority rule for quantum computing as well. However, it is known that for general quantum computing, this scheme does not work. In this paper, we provide a simplified explanation of this impossibility....
s the theory. In practice, researchers have been laboring for years to prove conclusively that a quantum computer can do something even the most capable conventional one can’t. Google’s effort has been led by John Martinis, who has done pioneering work in the use of superconducting circuits...
How does QKD work? QKD works by transmitting many light particles, orphotons, over fiber optic cables between parties. Each photon has a random quantum state, and collectively, the photons sent make up a stream of ones and zeros. This stream of ones and zeros are calledqubits-- the equival...

The evidence also suggests that while it’s hard, replicating outlier success is not impossible. IARPA arguably has been reasonably successful –David Wineland’s Nobel prize winning quantum computing work was sponsored by IARPA and I suspect that IARPA is positioned to be to quantum computing what...
