Free-standing silicon shadow masks for transmon qubit fabrication
I. Tsioutsios, K. Serniak, S. Diamond +6
Nanofabrication techniques for superconducting qubits rely on resist-based masks patterned by electron-beam or optical lithography. We have developed an alternative nanofabrication…
Continuous monitoring of a trapped, superconducting spin
M. Hays, V. Fatemi, K. Serniak +7
Readout and control of fermionic spins in solid-state systems are key primitives of quantum information processing and microscopic magnetic sensing. The highly localized nature of…
Direct Dispersive Monitoring of Charge Parity in Offset-Charge-Sensitive Transmons
K. Serniak, S. Diamond, M. Hays +5
A striking characteristic of superconducting circuits is that their eigenspectra and intermode coupling strengths are well predicted by simple Hamiltonians representing combination…
Hot non-equilibrium quasiparticles in transmon qubits
K. Serniak, M. Hays, G. de Lange +6
Non-equilibrium quasiparticle excitations degrade the performance of a variety of superconducting circuits. Understanding the energy distribution of these quasiparticles will yield…
