A Memory Hierarchy for Many-Body Localization: Emulating the Thermodynamic Limit
Alex Nico-Katz, Abolfazl Bayat, Sougato Bose
Local memory - the ability to extract information from a subsystem about its initial state - is a central feature of many-body localization. We introduce, investigate, and compare…
Improving resilience of the Quantum Gravity Induced Entanglement of Masses (QGEM) to decoherence using 3 superpositions
Martine Schut, Jules Tilly, Ryan J. Marshman +2
Recently a protocol called quantum gravity induced entanglement of masses (QGEM) that aims to test the quantum nature of gravity using the entanglement of 2 qubits was proposed. Th…
Voltage-controlled Hubbard spin transistor
Rozhin Yousefjani, Sougato Bose, Abolfazl Bayat
Transistors are key elements for enabling computational hardware in both classical and quantum domains. Here, we propose a voltage-gated spin transistor using itinerant electrons i…
Constructing Nano-Object Quantum Superpositions with a Stern-Gerlach Interferometer
Ryan J. Marshman, Anupam Mazumdar, Ron Folman +1
Probing quantum mechanics, quantum aspects of general relativity along with the sensing and the constraining of classical gravity can all be enabled by unprecedented spatial sizes…
Qudits for Witnessing Quantum Gravity Induced Entanglement of Masses Under Decoherence
Jules Tilly, Ryan J. Marshman, Anupam Mazumdar +1
Recently a theoretical and an experimental protocol known as quantum gravity induced entanglement of masses (QGEM) has been proposed to test the quantum nature of gravity using two…
