Non-Demolition Dispersive Measurement of a Superconducting Qubit with a Microstrip SQUID Amplifier
G. P. Berman, D. I. Kamenev, D. Kinion +1
We have studied the possibility of a single-shot non-demolition measurement of a superconducting qubit using a microstrip SQUID amplifier (MSA). The Johnson noise generated by all…
Modeling and Simulation of a Microstrip-SQUID Amplifier
G. P. Berman, O. O. Chumak, D. I. Kamenev +2
Using a simple lumped-circuit model, we numerically study the dependence of the voltage gain and noise on the amplifier's parameters. Linear, quasi-linear, and nonlinear regimes ar…
Influence of qubit displacements on quantum logic operations in a silicon-based quantum computer with constant interaction
D. I. Kamenev, G. P. Berman, V. I. Tsifrinovich
The errors caused by qubit displacements from their prescribed locations in an ensemble of spin chains are estimated analytically and calculated numerically for a quantum computer…
Creation of entanglement in a scalable spin quantum computer with long-range dipole-dipole interaction between qubits
D. I. Kamenev, G. P. Berman, V. I. Tsifrinovich
Creation of entanglement is considered theoretically and numerically in an ensemble of spin chains with dipole-dipole interaction between the spins. The unwanted effect of the long…
Implementation of quantum logic operations and creation of entanglement in a silicon-based quantum computer with constant interaction
G. P. Berman, G. W. Brown, M. E. Hawley +2
We describe how to implement quantum logic operations in a silicon-based quantum computer with phosphorus atoms serving as qubits. The information is stored in the states of nuclea…
Quantum logic operations and creation of entanglement in a scalable superconducting quantum computer with long-range constant interaction between qubits
G. P. Berman, A. R. Bishop, D. I. Kamenev +1
We consider a one-dimensional chain of many superconducting quantum interference devices (SQUIDs), serving as charge qubits. Each SQUID is coupled to its nearest neighbors through…
