Superconducting Circuits and Quantum Computation
... Evan Moran Here we use superconducting circuits as components for quantum computing and as model systems for non-linear dynamics. Quantum computation holds the potential to solve problems currently intractable with today’s computers. Information in a quantum computer is stored on quantum variables, ...

A quantum delayed choice experiment
... We also measured the negative-valued minimum value of the WF as a function of delay T, with the WF measured after R2 but without reading out the test qubit state. For γT=1/3, the field amplitude is reduced by only 15%, but the absolute value of the minimum negative value of the WF almost decays to 0 ...

Experimental Bell Inequality Violation with an Atom and a Photon

The famous 1935 Einstein-Podolsky-Rosen thought experiment showed how measurements of certain entangled quantum systems require a nonlocal description of nature [1], thus leading to the suggestion that quantum mechanics is incomplete. However, starting in 1965, Bell and others discovered that certai ...
