Quantum matrix arithmetics with Hamiltonian evolution
Christopher Kang, Yuan Su
The efficient implementation of matrix arithmetic operations underpins the speedups of many quantum algorithms. We develop a suite of methods to perform matrix arithmetics -- with…
In Situ Quantum Analog Pulse Characterization via Structured Signal Processing
Yulong Dong, Christopher Kang, Murphy Yuezhen Niu
Analog quantum simulators can directly emulate time-dependent Hamiltonian dynamics, enabling the exploration of diverse physical phenomena such as phase transitions, quench dynamic…
The FLuid Allocation of Surface code Qubits (FLASQ) cost model for early fault-tolerant quantum algorithms
William J. Huggins, Tanuj Khattar, Amanda Xu +6
Holistic resource estimates are essential for guiding the development of fault-tolerant quantum algorithms and the computers they will run on. This is particularly true when we foc…
Leveraging Hamiltonian Simulation Techniques to Compile Operations on Bosonic Devices
Christopher Kang, Micheline B. Soley, Eleanor Crane +2
Circuit QED enables the combined use of qubits and oscillator modes. Despite a variety of available gate sets, many hybrid qubit-boson (i.e., oscillator) operations are realizable…
