Architectures for Multinode Superconducting Quantum Computers
James Ang, Gabriella Carini, Yanzhu Chen +30
Many proposals to scale quantum technology rely on modular or distributed designs where individual quantum processors, called nodes, are linked together to form one large multinode…
Minimum Trotterization Formulas for a Time-Dependent Hamiltonian
Tatsuhiko N. Ikeda, Asir Abrar, Isaac L. Chuang +1
When a time propagator for duration consists of two noncommuting parts , Trotterization approximately decomposes the propagator into a product of exponential…
Multivariable quantum signal processing (M-QSP): prophecies of the two-headed oracle
Zane M. Rossi, Isaac L. Chuang
Recent work shows that quantum signal processing (QSP) and its multi-qubit lifted version, quantum singular value transformation (QSVT), unify and improve the presentation of most…
Learning Noise via Dynamical Decoupling of Entangled Qubits
Trevor McCourt, Charles Neill, Kenny Lee +8
Noise in entangled quantum systems is difficult to characterize due to many-body effects involving multiple degrees of freedom. This noise poses a challenge to quantum computing, w…
