A Qutrit Time Crystal Stabilized with Native Chiral Interactions
Noah Goss, Nishchay Suri, Brian Marinelli +11
Periodically driven quantum many-body systems can spontaneously break discrete time-translation symmetry, realizing discrete time crystals. To date, both experimental and theoretic…
Understanding Quantum Instruments
Akel Hashim
The quantum instrument (QI) formalism is required to model mid-circuit measurements (MCMs) and the dependence of the post-measurement state on the measurement outcome. Correctly mo…
Advances in Josephson Junction Materials and Processes Toward Practical Quantum Computing
Hyunseong Kim, Gyunghyun Jang, Seungwon Jin +8
The Josephson junction is the fundamental nonlinear building block of superconducting quantum technologies. Its macroscopic quantum tunneling physics underpins superconducting quan…
Time-series based quantum state discrimination
Samuel Jung, Neel Vora, Akel Hashim +2
Accurate quantum state readout is crucial for error correction and algorithms, but measurement errors are detrimental. Readout fidelity is typically limited by a poor signal-to-noi…
Easier randomizing gates provide more accurate fidelity estimation
Debankan Sannamoth, Kristine Boone, Arnaud Carignan-Dugas +4
Accurate benchmarking of quantum gates is crucial for understanding and enhancing the performance of quantum hardware. A standard method for this is interleaved benchmarking, a tec…
Efficient Generation of Multi-partite Entanglement between Non-local Superconducting Qubits using Classical Feedback
Akel Hashim, Ming Yuan, Pranav Gokhale +8
Quantum entanglement is one of the primary features which distinguishes quantum computers from classical computers. In gate-based quantum computing, the creation of entangled state…
