Generalizing measurement-induced phase transitions to information exchange symmetry breaking
Shane P. Kelly, Jamir Marino
In this work we investigate the conditions for quantum back action to result in a phase transition in the information dynamics of a monitored system. We introduce a framework that…
Markovian to non-Markovian phase transition in the operator dynamics of a mobile impurity
Dominic Gribben, Jamir Marino, Shane P. Kelly
We study a random unitary circuit model of an impurity moving through a chaotic medium. The exchange of information between the medium and impurity is controlled by varying the vel…
Entanglement transitions induced by quantum-data collection
Shane P. Kelly, Jamir Marino
We present an entanglement transition in an array of qubits, induced by the transfer of quantum information from a system to a quantum computer. This quantum-data collection is an…
Scrambling Transition in a Radiative Random Unitary Circuit
Zack Weinstein, Shane P. Kelly, Jamir Marino +1
We study quantum information scrambling in a random unitary circuit that exchanges qubits with an environment at a rate . As a result, initially localized quantum information no…
Coherence requirements for quantum communication from hybrid circuit dynamics
Shane P. Kelly, Ulrich Poschinger, Ferdinand Schmidt-Kaler +2
The coherent superposition of quantum states is an important resource for quantum information processing which distinguishes quantum dynamics and information from their classical c…
Quantum memory at an eigenstate phase transition in a weakly chaotic model
M. R. Lambert, Shan-Wen Tsai, Shane P. Kelly
We study a fully connected quantum spin model resonantly coupled to a small environment of non-interacting spins, and investigate how initial state properties are remembered at lon…
Disorder-free localization in quantum walks
B. Danacı, İ. Yalçınkaya, B. Çakmak +3
The phenomenon of localization usually happens due to the existence of disorder in a medium. Nevertheless, certain quantum systems allow dynamical localization solely due to the na…
Thermalization and its Breakdown for a Large Nonlinear Spin
Shane P. Kelly, Eddy Timmermans, S. -W. Tsai
By developing a semi-classical analysis based on the Eigenstate Thermalization Hypothesis, we determine the long time behavior of a large spin evolving with a nonlinear Hamiltonian…
Detecting Macroscopic Indefiniteness of Cat States in Bosonic Interferometers
Shane P. Kelly, Eddy Timmermans, S. W. Tsai
The paradigm of Schrödinger's cat illustrates how quantum states preclude the assignment of definite properties to a macroscopic object (realism). In this work we develop a method…
