Measurement-based quantum thermal machines with feedback control
Bibek Bhandari, Robert Czupryniak, Paolo Andrea Erdman +1
We investigate coupled-qubit-based thermal machines powered by quantum measurements and feedback. We consider two different versions of the machine: 1) a quantum Maxwell's demon wh…
Programmable Heisenberg interactions between Floquet qubits
Long B. Nguyen, Yosep Kim, Akel Hashim +9
The fundamental trade-off between robustness and tunability is a central challenge in the pursuit of quantum simulation and fault-tolerant quantum computation. In particular, many…
Particle current statistics in driven mesoscale conductors
Marlon Brenes, Giacomo Guarnieri, Archak Purkayastha +3
We propose a highly-scalable method to compute the statistics of charge transfer in driven conductors. The framework can be applied in situations of non-zero temperature, strong co…
A quantum register using collective excitations in a Bose-Einstein condensate
Elisha Haber, Zekai Chen, Nicholas P. Bigelow
A qubit made up of an ensemble of atoms is attractive due to its resistance to atom losses, and many proposals to realize such a qubit are based on the Rydberg blockade effect. In…
Quantum State Driving along Arbitrary Trajectories
Le Hu, Andrew N. Jordan
Starting with the quantum brachistochrone problem of the infinitesimal form, we solve the minimal time and corresponding time-dependent Hamiltonian to drive a pure quantum state wi…
Anomalous energy exchanges and Wigner function negativities in a single qubit gate
Maria Maffei, Cyril Elouard, Bruno O. Goes +3
Anomalous weak values and Wigner function's negativity are well known witnesses of quantum contextuality. We show that these effects occur when analyzing the energetics of a single…
Experimental generation of polarization entanglement from spontaneous parametric down-conversion pumped by spatiotemporally highly incoherent light
Cheng Li, Boris Braverman, Girish Kulkarni +1
The influence of pump coherence on the entanglement produced in spontaneous parametric down-conversion (SPDC) is important to understand, both from a fundamental perspective, and f…
Unexpected Robustness of Multipartite Entanglement against Sudden Death from Spontaneous Emission
Songbo Xie, Daniel Younis, Joseph H. Eberly
Entanglement is known to decay even in isolated systems, an effect attributed to spontaneous emission. This fragility of entanglement can be exacerbated by entanglement sudden deat…
Quasi-Diabatic Propagation Scheme for Simulating Polariton Chemistry
Deping Hu, Arkajit Mandal, Braden M. Weight +1
We generalize the quasi-diabatic (QD) propagation scheme to simulate the non-adiabatic polariton dynamics in molecule-cavity hybrid systems. The adiabatic-Fock states, which are th…
Super-phenomena in arbitrary quantum observables
Andrew N. Jordan, Yakir Aharonov, Daniele C. Struppa +6
Superoscillations occur when a globally band-limited function locally oscillates faster than its highest Fourier coefficient. We generalize this effect to arbitrary quantum mechani…
Contextuality and Quantum Discord
Asma Al-Qasimi
One of the defining differences between classical and quantum systems is how measurements affect them. Here, we compare the approaches of contextuality and quantum discord in captu…
Post-selection and quantum energetics
Spencer Rogers, Andrew N. Jordan
We investigate the anomalous energy change of the measurement apparatus when a qubit is measured in bases that do not commute with energy. We model two possible measurement impleme…
Managing the Three-Party Entanglement Challenge
Songbo Xie, J. H. Eberly
We introduce the challenges of multi-party quantum entanglement and explain a recent success in learning to take its measure. Given the widely accepted reputation of entanglement a…
Experimental Examination of Entanglement Estimates
Songbo Xie, Yuan-Yuan Zhao, Chao Zhang +4
Recently a proper genuine multipartite entanglement (GME) measure has been found for three-qubit pure states [see Xie and Eberly, Phys. Rev. Lett. 127, 040403 (2021)], but capturin…
Fisher information of correlated stochastic processes
Marco Radaelli, Gabriel T. Landi, Kavan Modi +1
Many real-world tasks include some kind of parameter estimation, i.e., determination of a parameter encoded in a probability distribution. Often, such probability distributions ari…
Energy-efficient quantum non-demolition measurement with a spin-photon interface
Maria Maffei, Bruno O. Goes, Stephen C. Wein +3
Spin-photon interfaces (SPIs) are key devices of quantum technologies, aimed at coherently transferring quantum information between spin qubits and propagating pulses of polarized…
Thermodynamics of Quantum Measurement and the Demon's Arrow of Time
Kagan Yanik, Bibek Bhandari, Sreenath K. Manikandan +1
We discuss the thermodynamic aspects of a single qubit based device, powered by weak quantum measurements, and feedback controlled by a quantum Maxwell's demon. We discuss both dis…
Analog Quantum Simulation of the Dynamics of Open Quantum Systems with Quantum Dots and Microelectronic Circuits
Chang Woo Kim, John M. Nichol, Andrew N. Jordan +1
We introduce a general setup for the analog quantum simulation of the dynamics of open quantum systems based on semiconductor quantum dots electrically connected to a chain of quan…
Quantum Telescopy Clock Games
Robert Czupryniak, Eric Chitambar, John Steinmetz +1
We consider the clock game-a task formulated in the framework of quantum information theory-that can be used to improve the existing schemes of quantum-enhanced telescopy. The prob…
Energetic cost of measurements using quantum, coherent, and thermal light
Xiayu Linpeng, Léa Bresque, Maria Maffei +3
Quantum measurements are basic operations that play a critical role in the study and application of quantum information. We study how the use of quantum, coherent, and classical th…
Achieving Heisenberg Scaling on Measurement of A Three-Qubit System via Quantum Error Correction
Le Hu, Shengshi Pang, Andrew Jordan
In many-body quantum systems, the quantum Fisher information an observer can obtain is susceptible to decoherence. Consequently, quantum enhanced metrology, such as Heisenberg scal…
Isolating noise and amplifying signal with quantum Cheshire cat
Ahana Ghoshal, Soham Sau, Debmalya Das +1
The so-called quantum Cheshire cat is a phenomenon in which an object, identified with a "cat", is dissociated from a property of the object, identified with the "grin" of the cat.…
