We designed a 30 A/cm2 RSFQ-qubit control circuit and tested operation at 4 K. The integration of RSFQ technology and qubits monolithically requires great attention to thermal budgeting and electromagnetic compatibility. These issues are of primary c

We present and demonstrate experimentally a persistent-current bias loop that is intended to provide an on-chip stable dc magnetic field to flux-bias the flux qubits in a superconducting quantum computer. The bias loop is initialized to approximately

A general framework is presented to study nondistortion quantum interrogation (abbreviated NQI) in which process the unknown internal state of the quantum object being detected is not disturbed. The successful probabilities in single-shot and two-sho

We use the thermal activation of Josephson junctions as a thermometer to investigate heat flow from a hot resistor at milliKelvin temperatures on a silicon chip used for superconducting qubit experiments. The experiments are compared to computer simu

We study the dynamics of a current biased Josephson phase qubit capacitively coupled to an LC circuit. We find that the eigenstates of this system are dressed states that are entangled states between the phase qubit and the LC resonator. We demonstra

The unshunted single-flux-quantum SFQ comparator is described for the first time. Its dynamic behavior is surprisingly similar to the familiar resistively-shunted SFQ comparator. For certain parameter ranges both junctions of the comparator may pulse

Niobium based rapid-single-flux-quantum (RSFQ) digital circuits generally operate at temperature 4 K. It is desirable to develop RSFQ circuits for operation at much lower temperatures, in particular to use as control and interface circuitry for super

We design an RSFQ oscillator with a variable duty cycle to drive a superconductive qubit. This design has been optimized to minimize the decoherence when coupled to the superconductive persistent current qubit. A continuous RSFQ ring oscillator reads

Superconducting quantum circuits have been proposed as qubits for developing quantum computation. The goal is to use superconducting quantum circuits to model the measurement process, understand the sources of decoherence, and to develop scalable alg

According to quantum theory, microscopic objects exist in a superposition of distinct states until they are “observed”. Nobody knows whether such quantum coherence can actually exist in a macroscopic system. In the experiment described here, a su
