Reduced density matrix and entanglement Hamiltonian for a free real scalar field on an interval
Mikhail A. Baranov
An exact result for the reduced density matrix on a finite interval for a dimensional free real scalar field in the ground state is presented. In the massless case, the Willi…
Probing infinite many-body quantum systems with finite-size quantum simulators
Viacheslav Kuzmin, Torsten V. Zache, Christian Kokail +4
Experimental studies of synthetic quantum matter are necessarily restricted to approximate ground states prepared on finite-size quantum simulators. In general, this limits their r…
Monitoring Quantum Simulators via Quantum Non-Demolition Couplings to Atomic Clock Qubits
Denis V. Vasilyev, Andrey Grankin, Mikhail A. Baranov +2
We discuss monitoring the time evolution of an analog quantum simulator via a quantum non-demolition (QND) coupling to an auxiliary `clock' qubit. The QND variable of interest is t…
Quantum Scanning Microscope for Cold Atoms
Dayou Yang, Denis V. Vasilyev, Catherine Laflamme +2
We present a detailed theoretical description of an atomic scanning microscope in a cavity QED setup proposed in Phys. Rev. Lett. 120, 133601 (2018). The microscope continuously ob…
Theory of a Quantum Scanning Microscope for Cold Atoms
Dayou Yang, Catherine Laflamme, Denis Vasilyev +2
We propose and analyze a scanning microscope to monitor `live' the quantum dynamics of cold atoms in a Cavity QED setup. The microscope measures the atomic density with subwaveleng…
Majoranas in Noisy Kitaev Wires
Ying Hu, Zi Cai, Mikhail A. Baranov +1
Robustness of edge states and non-Abelian excitations of topological states of matter promises quantum memory and quantum processing, which is naturally immune against microscopic…
