Linear combination of Hamiltonian simulation for non-unitary dynamics with optimal state preparation cost
Abstract: We propose a simple method for simulating a general class of non-unitary dynamics as a linear combination of Hamiltonian simulation (LCHS) problems. LCHS does not rely on converting the pro...

Engineering Hierarchical Symmetries and Massive Nambu-Goldstone Modes
Abstract: We present a general driving protocol for many-body systems to generate a sequence of prethermal regimes, each exhibiting a lower symmetry than the preceding one [1]. We provide an explicit...

High fidelity hybrid quantum computing platform based on single quanta of sound
Abstract: Entanglement and superposition are fundamental properties of quantum-mechanical states, with no classical counterparts. It is well-established that elementary particles, such as electrons a...
