متن کاملUniversal gates for non-unitary quantum circuit
Quantum circuit is generalized to include non-unitary gates which are operated by quantum measurement. A 1-qubit non-unitary gate, together with the controlled-NOT gate and the 1-qubit unitary gate, is shown to constitute a universal set of gates for the non-unitary quantum circuit that reduces the number of the overhead of qubits required to ensure fault tolerance. A reversing measurement sche...
متن کاملPhoton-number squeezing in circuit quantum electrodynamics.
A superconducting single-electron transistor (SSET) coupled to an anharmonic oscillator, e.g., a Josephson junction-L-C circuit, can drive the latter to a nonequilibrium photon-number distribution. By biasing the SSET at the Josephson quasiparticle cycle, cooling of the oscillator as well as a laserlike enhancement of the photon number can be achieved. Here, we show that the cutoff in the quasi...
متن کاملOptimal quantum circuit synthesis from controlled-unitary gates
Using a geometric approach, we derive the minimum number of applications needed for an arbitrary controlled-unitary gate to construct a universal quantum circuit. An analytic construction procedure is presented and shown to be either optimal or close to optimal. This result can be extended to improve the efficiency of universal quantum circuit construction from any entangling gate. In addition,...
متن کاملA Class of Efficient Quantum Incrementer Gates for Quantum Circuit Synthesis
The quantum incrementer is one of the simplest quantum operators, which exhibits basic arithmetic operations such as addition, the propagation of carry qubits and the resetting of carry qubits. In this paper, three quantum incrementer gate circuit topologies are derived and compared based upon their total number of gates, the complexity of the circuits, the types of gates used and the number of...
