Scaling Laws of Quantum Information Lifetime in Monitored Quantum Dynamics
Bingzhi Zhang, Fangjun Hu, Runzhe Mo +3
Quantum information is typically fragile under measurements and environmental coupling. Remarkably, we find that its lifetime can scale exponentially with system size when the envi…
Long-time soliton dynamics via a coarse-grained space-time method
Dung N. Pham, Zoe Zager, Wentao Fan +1
We investigate the long-time dynamics of the Sine-Gordon (SG) model under a class of perturbations whose quantum field theoretic analog - via bosonization - corresponds to the mass…
Model Order Reduction for Open Quantum Systems Based on Measurement-adapted Time-coarse Graining
Wentao Fan, Hakan E. Türeci
Model order reduction encompasses mathematical techniques aimed at reducing the complexity of mathematical models in simulations while retaining the essential characteristics and b…
A neural processing approach to quantum state discrimination
Saeed A. Khan, Fangjun Hu, Gerasimos Angelatos +2
Although linear quantum amplification has proven essential to the processing of weak quantum signals, extracting higher-order quantum features such as correlations in principle dem…
Systematic time-coarse graining for driven quantum systems
Leon Bello, Wentao Fan, Aditya Gandotra +1
Many recent advancements in quantum computing leverage strong drives on nonlinear systems for state preparation, signal amplification, or gate operation. However, the interplay wit…
Spectral Theory for Non-linear Superconducting Microwave Systems: Extracting Relaxation Rates and Mode Hybridization
Dung N. Pham, Richard D. Li, Hakan E. Türeci
The accurate modeling of mode hybridization and calculation of radiative relaxation rates have been crucial to the design and optimization of superconducting quantum devices. In th…
Radiative Properties of an Artificial Atom coupled to a Josephson Junction Array
Kanu Sinha, Saeed A. Khan, Elif Cüce +1
We study the radiative properties -- the Lamb shift, Purcell decay rate and the spontaneous emission dynamics -- of an artificial atom coupled to a long, multimode cavity formed by…
Physical reservoir computing using finitely-sampled quantum systems
Saeed Ahmed Khan, Fangjun Hu, Gerasimos Angelatos +1
The paradigm of reservoir computing exploits the nonlinear dynamics of a physical reservoir to perform complex time-series processing tasks such as speech recognition and forecasti…
Purification and switching protocols for dissipatively stabilized entangled qubit states
Sven M. Hein, Camille Aron, Hakan E. Türeci
Pure dephasing processes limit the fidelities achievable in driven-dissipative schemes for stabilization of entangled states of qubits. We propose a scheme which, combined with alr…
Beyond Strong Coupling in a Massively Multimode Cavity
Neereja M. Sundaresan, Yanbing Liu, Darius Sadri +5
The study of light-matter interaction has seen a resurgence in recent years, stimulated by highly controllable, precise, and modular experiments in cavity quantum electrodynamics (…
Gain-tunable optomechanical cooling in a laser cavity
Li Ge, Sanli Faez, Florian Marquardt +1
We study the optical cooling of the resonator mirror in a cavity-optomechanical system that contains an optical gain medium. We find that the optical damping rate is vanishingly sm…
