Decoherence in Solid State Qubits
Interaction of solid state qubits with environmental degrees of freedom strongly affects the qubit dynamics, and leads to decoherence. In quantum information processing with solid state qubits, decoherence significantly limits the performances of such devices. Therefore, it is necessary to fully understand the mechanisms that lead to decoherence. In this review we discuss how decoherence affect...

متن کاملEntanglement of solid-state qubits by measurement
We show that two identical solid-state qubits can be made fully entangled ~starting from a completely mixed state! with probability 1/4 just by measuring them with a detector, equally coupled to the qubits. This happens in the case of repeated strong ~projective! measurements as well as in a more realistic case of weak continuous measurement. In the latter case, the entangled state can be ident...
متن کاملProjective Measurement Scheme for Solid-State Qubits
We present an effective measurement scheme for the solid-state qubits that does not introduce extra decoherence to the qubits until the measurement is switched on by a resonant pulse. The resonant pulse then maximally entangles the qubit with the detector. The scheme has the feature of being projective, noiseless, and switchable. This method is illustrated on the superconducting persistent-curr...
متن کاملPerspectives on Solid-State Flying Qubits
The quest for quantum-computing capable architectures has recently focused on solid-state implementations, since they seem more prone to meet the required criteria [1] of scalability and integrability than alternative approaches like the ones based on nuclear magnetic resonance, ion traps or quantum electrodynamics techniques [2]. In many proposals different components of a quantum-computing sy...
