Development of transmon qubits solely from optical lithography on 300mm wafers
N. Foroozani, C. Hobbs, C. C. Hung +21
Qubit information processors are increasing in footprint but currently rely on e-beam lithography for patterning the required Josephson junctions (JJs). Advanced optical lithograph…
Microring resonator-coupled photoluminescence from silicon W~centers
A. N. Tait, S. M. Buckley, J. Chiles +6
Defect centers are promising candidates for waveguide-integrated silicon light sources. We demonstrate microresonator- and waveguide-coupled photoluminescence from silicon W~center…
Dark Matter Search Results from the PICO-60 CF Bubble Chamber
C. Amole, M. Ardid, I. J. Arnquist +59
New results are reported from the operation of the PICO-60 dark matter detector, a bubble chamber filled with 52 kg of CF located in the SNOLAB underground laboratory. As i…
A Race Track Trapped-Ion Quantum Processor
S. A. Moses, C. H. Baldwin, M. S. Allman +93
We describe and benchmark a new quantum charge-coupled device (QCCD) trapped-ion quantum computer based on a linear trap with periodic boundary conditions, which resembles a race t…
Improved dark matter search results from PICO-2L Run 2
C. Amole, M. Ardid, I. J. Arnquist +55
New data are reported from a second run of the 2-liter PICO-2L CF bubble chamber with a total exposure of 129kg-days at a thermodynamic threshold energy of 3.3keV.…
