Quantum Simulation via Stochastic Combination of Unitaries
Joseph Peetz, Scott E. Smart, Prineha Narang
Quantum simulation algorithms often require numerous ancilla qubits and deep circuits, prohibitive for near-term hardware. We introduce a framework for simulating quantum channels…
Tunable Non-Gaussian Mechanical States in a Strongly Coupled Hybrid Quantum System
Jugal Talukdar, Scott E. Smart, Prineha Narang
Quantum states of motion are critical components in the second quantum revolution. We investigate the generation and control of non-Gaussian motional states in a tripartite hybrid…
Unitary Dilation Strategy Towards Efficient and Exact Simulation of Non-Unitary Quantum Evolutions
Aman Mehta, Scott E. Smart, Joseph Peetz +2
Simulating quantum systems with their environments often requires non-unitary operations, and mapping these to quantum devices often involves expensive dilations or prohibitive mea…
Learning Orthogonal Random Unitary Channels with Contracted Quantum Approaches and Simplex Optimization
Scott E. Smart, Alexander Jürgens, Joseph Peetz +1
Random (mixed) unitary channels describe an important subset of quantum channels, which are commonly used in quantum information, noise modeling, and quantum error mitigation. Desp…
