متن کاملQuantum Nondemolition Monitoring of Universal Quantum Computers
It is proved that the halt scheme for a universal quantum computer originally proposed by Deutsch works without spoiling the computation. The “conflict” pointed out recently by Myers in the defintion of a universal quantum computer is shown to be only apparent. In the context of quantum nondemolition (QND) measurement, it is also shown that the output observable, an observable representing the ...
متن کاملPolarization preserving quantum nondemolition photodetector
A polarization preserving quantum nondemolition photodetector is proposed based on nonlinearities obtainable through quantum coherence effects. An atomic level scheme is devised such that in the presence of strong linearly polarized drive field a coherent weak probe field acquires a phase proportional to the number of photons in the signal mode immaterial of its polarization state. It is also s...
متن کاملQuantum nondemolition circuit for testing bipartite complementarity.
We present a quantum circuit that implements a nondemolition measurement of complementary single- and bipartite properties of a two-qubit system: entanglement and single-partite visibility and predictability. The system must be in a pure state with real coefficients in the computational basis, which allows a direct operational interpretation of those properties. The circuit can be realized in m...
متن کاملDemonstration of a quantum nondemolition sum gate.
The sum gate is the canonical two-mode gate for universal quantum computation based on continuous quantum variables. It represents the natural analogue to a qubit C-NOT gate. In addition, the continuous-variable gate describes a quantum nondemolition (QND) interaction between the quadrature components of two light modes. We experimentally demonstrate a QND sum gate, employing the scheme by R. F...
