چکیده

Quantum computation algorithms promise of enormous speed up in dealing with certain classes of problems [1,2] can only be realized if a quantum computing device is built on a scale of at least several thousand qubits. The inherent scalability of solid state devices and high level of expertise existing in industrial electronics and experimental mesoscopic physics make solid state-based quantum computers an attractive choice [3,4]. The problem of quantum coherence preservation in such devices, in the presence of macroscopic number of degrees of freedom, is difficult but at least theoretically solvable [3,4]. Moreover, in a recent experiment on a superconducting quantum dot (single electron transistor, SET) [5] coherent quantum beats were demonstrated in this mesoscopic system, which proves its suitability as a qubit prototype.

Fast universal quantum gates on microwave photons with all-resonance operations in circuit QED

Stark shift on a superconducting qubit in circuit quantum electrodynamics (QED) has been used to construct universal quantum entangling gates on superconducting resonators in previous works. It is a second-order coupling effect between the resonator and the qubit in the dispersive regime, which leads to a slow state-selective rotation on the qubit. Here, we present two proposals to construct th...

Quantum Logic Gates in Superconducting Qubits

Successful operation of a quantum computer will require unprecedented control of quantum systems. The basic qubit operations, quantum logic gates, are described by the linear Schrodinger equation: the “analog” nature of quantum state evolution makes these logic gates fundamentally sensitive to imperfections in control and loss of energy. In contrast, conventional digital logic can correct error...

Quantum Process Tomography of a Universal Entangling Gate Implemented with Josephson Phase Qubits

Quantum logic gates must perform properly when operating on their standard input basis states, as well as when operating on complex superpositions of these states. Experiments using superconducting qubits have validated the truth table for particular implementations of e.g. the controlled-NOT gate 1,2 , but have not fully characterized gate operation for arbitrary superpositions of input states...

Protocol for Universal Gates in Optimally Biased Superconducting Qubits

0031-9007= We present a new experimental protocol for performing universal gates in a register of superconducting qubits coupled by fixed on-chip linear reactances. The qubits have fixed, detuned Larmor frequencies and can remain, during the entire gate operation, biased at their optimal working point where decoherence due to fluctuations in control parameters is suppressed to first order. Two-...
