Simulation of quantum optics by coherent state decomposition
Jeffrey Marshall, Namit Anand
We introduce a framework for simulating quantum optics by decomposing the system into a finite rank (number of terms) superposition of coherent states. This allows us to define a r…
Scrambling and operator entanglement in local non-Hermitian quantum systems
Brian Barch, Namit Anand, Jeffrey Marshall +2
The breakdown of Lieb-Robinson bounds in local, non-Hermitian quantum systems opens up the possibility for a rich landscape of quantum many-body phenomenology. We elucidate this by…
Master Equation Emulation and Coherence Preservation with Classical Control of a Superconducting Qubit
Evangelos Vlachos, Haimeng Zhang, Vivek Maurya +3
Open quantum systems are a topic of intense theoretical research. The use of master equations to model a system's evolution subject to an interaction with an external environment i…
Towards solving the Fermi-Hubbard model via tailored quantum annealers
Ryan Levy, Zoe Gonzalez Izquierdo, Zhihui Wang +8
The Fermi-Hubbard model (FHM) on a two dimensional square lattice has long been an important testbed and target for simulating fermionic Hamiltonians on quantum hardware. We presen…
Suppressing quantum errors by scaling a surface code logical qubit
Rajeev Acharya, Igor Aleiner, Richard Allen +154
Practical quantum computing will require error rates that are well below what is achievable with physical qubits. Quantum error correction offers a path to algorithmically-relevant…
Two-Unitary Decomposition Algorithm and Open Quantum System Simulation
Nishchay Suri, Joseph Barreto, Stuart Hadfield +3
Simulating general quantum processes that describe realistic interactions of quantum systems following a non-unitary evolution is challenging for conventional quantum computers tha…
