Hardware optimized parity check gates for superconducting surface codes
Matthew J. Reagor, Thomas C. Bohdanowicz, David Rodriguez Perez +2
Error correcting codes use multi-qubit measurements to realize fault-tolerant quantum logic steps. In fact, the resources needed to scale-up fault-tolerant quantum computing hardwa…
Navigating the noise-depth tradeoff in adiabatic quantum circuits
Daniel Azses, Maxime Dupont, Bram Evert +2
Adiabatic quantum algorithms solve computational problems by slowly evolving a trivial state to the desired solution. On an ideal quantum computer, the solution quality improves mo…
Characterization of Nb films for superconducting qubits using phase boundary measurements
Kevin M. Ryan, Carlos G. Torres-Castanedo, Dominic P. Goronzy +8
Continued advances in superconducting qubit performance require more detailed understandings of the many sources of decoherence. Within these devices, two-level systems arise due t…
Simulating long-range coherence of atoms and photons in quantum computers
Emanuele G. Dalla Torre, Matthew J. Reagor
Lasers and Bose-Einstein condensates (BECs) exhibit macroscopic quantum coherence in seemingly unrelated ways. Lasers possess a well-defined global phase and are characterized by l…
An entanglement perspective on the quantum approximate optimization algorithm
Maxime Dupont, Nicolas Didier, Mark J. Hodson +2
Many quantum algorithms seek to output a specific bitstring solving the problem of interest--or a few if the solution is degenerate. It is the case for the quantum approximate opti…
Calibrating the Classical Hardness of the Quantum Approximate Optimization Algorithm
Maxime Dupont, Nicolas Didier, Mark J. Hodson +2
Trading fidelity for scale enables approximate classical simulators such as matrix product states (MPS) to run quantum circuits beyond exact methods. A control parameter, the so-ca…
Quantum computing hardware for HEP algorithms and sensing
M. Sohaib Alam, Sergey Belomestnykh, Nicholas Bornman +37
Quantum information science harnesses the principles of quantum mechanics to realize computational algorithms with complexities vastly intractable by current computer platforms. Ty…
Multi-modal electron microscopy study on decoherence sources and their stability in Nb based superconducting qubit
Jin-Su Oh, Xiaotian Fang, Tae-Hoon Kim +14
Niobium is commonly used for superconducting quantum systems as readout resonators, capacitors, and interconnects. The coherence time of the superconducting qubits is mainly limite…
Developing a Chemical and Structural Understanding of the Surface Oxide in a Niobium Superconducting Qubit
Akshay A. Murthy, Paul Masih Das, Stephanie M. Ribet +11
Superconducting thin films of niobium have been extensively employed in transmon qubit architectures. Although these architectures have demonstrated remarkable improvements in rece…
