Practical experimental certification of computational quantum gates via twirling
Osama Moussa, Marcus P. da Silva, Colm A. Ryan +1
Due to the technical difficulty of building large quantum computers, it is important to be able to estimate how faithful a given implementation is to an ideal quantum computer. The…
Measurements of Quasiparticle Tunneling Dynamics in a Bandgap-Engineered Transmon Qubit
L. Sun, L. DiCarlo, M. D. Reed +9
We have engineered the bandgap profile of transmon qubits by combining oxygen-doped Al for tunnel junction electrodes and clean Al as quasiparticle traps to investigate energy rela…
Coherence in a transmon qubit with epitaxial tunnel junctions
Martin P. Weides, Jeffrey S. Kline, Michael R. Vissers +5
We developed transmon qubits based on epitaxial tunnel junctions and interdigitated capacitors. This multileveled qubit, patterned by use of all-optical lithography, is a step towa…
Optical codeword demodulation with error rates below standard quantum limit using a conditional nulling receiver
Jian Chen, Jonathan L. Habif, Zachary Dutton +2
The quantum states of two laser pulses---coherent states---are never mutually orthogonal, making perfect discrimination impossible. Even so, coherent states can achieve the ultimat…
Resolved Near-Infrared Stellar Populations in Nearby Galaxies
Julianne J. Dalcanton, Benjamin F. Williams, Jason L. Melbourne +10
We present near-infrared (NIR) color-magnitude diagrams (CMDs) for the resolved stellar populations within 26 fields of 23 nearby galaxies (<4 Mpc), based on F110W and F160W images…
Polar codes for degradable quantum channels
Mark M. Wilde, Saikat Guha
Channel polarization is a phenomenon in which a particular recursive encoding induces a set of synthesized channels from many instances of a memoryless channel, such that a fractio…
