Quantum Reservoir Computing (QRC) uses quantum dynamics to efficiently process temporal data. In this work, we investigate a QRC framework based on two coupled Kerr nonlinear oscillators, a system well-suited for time-series prediction tasks due to i...
Wireless Josephson parametric amplifier above 20 GHz
Z. Hao, J. Cochran, Y. -C. Chang +2 more·Aug 15, 2025
Operating superconducting qubits at elevated temperatures offers increased cooling power and thus system scalability, but requires suppression of thermal photons to preserve coherence and readout fidelity. This motivates migration to higher operation...
Quantum Simulation of Collective Neutrino Oscillations in Dense Neutrino Environment
Shvetaank Tripathi, Sandeep Joshi, G. Rajpoot +1 more·Aug 15, 2025
Inside dense neutrino gases, such as neutron star mergers or core-collapse supernovae, collective neutrino effects cause the transformation of one neutrino flavour into another. Due to strong neutrino self-interactions in these environments, there is...
