Hadamard test (quantum computation)

In quantum computation, the Hadamard test is a method used to create a random variable whose expected value is the expected real part , where is a quantum state and is a unitary gate acting on the space of . The Hadamard test produces a random variable whose image is in and whose expected value is exactly . It is possible to modify the circuit to produce a random variable whose expected value is . (Wikipedia).

How To Test Quantum Gravity

Einstein's theory of gravity, General Relativity, is awesome. But strictly speaking it is wrong. We know that because it cannot handle the quantum behavior that particles have. To make quantum theory compatible with General Relativity, we need a theory of quantum gravity. We still don't ha

The quantum computers are coming - talk

Many people may not know it, but we live in a time where the first quantum computers have been created - and they're pretty damn cool. Why? Because while regular bits are limited to only two boring values, QBITs can take near infinite values and operate singularly or in harmony with each o
