Sampling quantum phase space with squeezed states.
We study the application of squeezed states in a quantum optical scheme for direct sampling of the phase space by photon counting. We prove that the detection setup with a squeezed coherent probe field is equivalent to the probing of the squeezed signal field with a coherent state. An example of the Schr odinger cat state measurement shows that the use of squeezed states allows one to detect cl...
متن کاملGeometric Quantum Computation on Solid-State Qubits
Geometric quantum computation is a scheme to use non-Abelian Holonomic operations rather than the conventional dynamic operations to manipulate quantum states for quantum information processing. Here we propose a geometric quantum computation scheme which can be realized with current technology on nanoscale Josephson-junction networks, known as a promising candidate for solid-state quantum comp...
متن کاملPhase-space Representation for Qubits
Problems involving interacting spins or qubits are often regarded as computationally intractable. These are frequently considered as only being accessible using quantum computers, which are not yet developed. At the same time, there is a ‘chicken and egg’ problem: it is difficult to design a quantum computer with no effective means to simulate its behaviour, including inevitable sources of loss...
متن کاملFlux-based superconducting qubits for quantum computation
Superconducting quantum circuits have been proposed as qubits for developing quantum computation. The goal is to use superconducting quantum circuits to model the measurement process, understand the sources of decoherence, and to develop scalable algorithms. A particularly promising feature of using superconducting technology is the potential of developing high-speed, on-chip control circuitry ...
متن کاملPicturing qubits in phase space
Focusing particularly on one-qubit and two-qubit systems, I explain how the quantum state of a system of n qubits can be expressed as a real function—a generalized Wigner function—on a discrete 2 × 2 phase space. The phase space is based on the finite field having 2 elements, and its geometric structure leads naturally to the construction of a complete set of 2 + 1 mutually conjugate bases. PAC...
