Quantum state conversion between continuous variable and qubits systems

We investigate how quantum state can be converted between continuous variable and qubits systems. Non-linear Jaynes-Cumings interaction Hamiltonian is introduced to accomplish the conversion. Detail analysis on the conversion of thermal state exhibits that pretty good fidelity can be achieved.

From Qubits to Continuous–Variable Quantum Computation

By encoding a qudit in a harmonic oscillator and investigating the d → ∞ limit, we give an entirely new realization of continuous–variable quantum computation. The generalized Pauli group is generated by number and phase operators for harmonic oscillators. The use of continuous–variable (CV) quantum computing allows information to be encoded and processed much more compactly and efficiently tha...

Conversion of entanglement between continuous variable and qubit systems

We investigate how entanglement can be transferred between continuous variable and qubit systems. We find that a two-mode squeezed vacuum state and a continuous variable Werner state can be converted to the product states of infinitive number of two-qubit states while keeping the entanglement. The reverse process is also possible. PACS: 03.67.Mn;03.65.Ud

Continuous-variable optical quantum state tomography

This review covers latest developments in continuous-variable quantum-state tomography of optical fields and photons, placing a special accent on its practical aspects and applications in quantum information technology. Optical homodyne tomography is reviewed as a method of reconstructing the state of light in a given optical mode. A range of relevant practical topics are discussed, such as sta...
