Very Low Temperature Measurement System for Quantum Computation with Superconductors
Abstract
Two dilution refrigerators have been installed and made operational for the purpose of having dedicated measurement systems one at MIT and the other at the University of Rochester for carrying out quantum computing experiments. Both systems are a Kelvinox 400 model from Oxford instruments, equipped with both dc and rf lines for measurements; and both systems are vibrationally isolated and magnetically and electrically shielded for low noise measurements. Within the first year these systems have been fitted with custom- designed sample spaces and wiring. Within less than a year, this equipment has enabled the researchers to demonstrate: quantum levels in a persistent current qubit, rf and dc spectroscopy of these energy levels, and control circuits using Single Flux Quantum circuits. This equipment is enhancing our research effort to study, design, demonstrate, and develop algorithms and quantum-coherent circuitry using magnetic-flux-based superconducting qubits.
