Anomalous Amplification of a Homodyne signal via Almost-Balanced Weak Values
Wei-Tao Liu, Julián Martínez-Rincón, Gerardo I. Viza +1
The technique of almost-balanced weak values amplification (ABWV) was recently proposed [Phys. Rev. Lett. 116: 100803 (2016)]. We demonstrate this technique using a modified Sagnac…
Cryogenic photoluminescence imaging system for nanoscale positioning of single quantum emitters
Jin Liu, Macelo Davanco, Luca Sapienza +5
We report a photoluminescence imaging system for locating single quantum emitters with respect to alignment features. Samples are interrogated in a 4~K closed-cycle cryostat by a h…
Experimental investigation of Popper's proposed ghost-diffraction experiment
Eliot Bolduc, Ebrahim Karimi, Kevin Piché +2
In an effort to challenge the Copenhagen interpretation of quantum mechanics, Karl Popper proposed an experiment involving spatially separated entangled particles. In this experime…
High-Dimensional Intra-City Quantum Cryptography with Structured Photons
Alicia Sit, Frédéric Bouchard, Robert Fickler +11
Quantum key distribution (QKD) promises information-theoretically secure communication, and is already on the verge of commercialization. Thus far, different QKD protocols have bee…
Weak Value Amplification Can Outperform Conventional Measurement in the Presence of Detector Saturation
Jérémie Harris, Robert W. Boyd, Jeff S. Lundeen
Weak value amplification (WVA) is a technique in which one can magnify the apparent strength of a measurement signal. Some have claimed that WVA can outperform more conventional me…
Quantum parameter estimation with the Landau-Zener transition
Jing Yang, Shengshi Pang, Andrew N. Jordan
We investigate the fundamental limits in precision allowed by quantum mechanics from Landau-Zener transitions, concerning Hamiltonian parameters. While the Landau-Zener transition…
Prediction and Characterization of Multiple Extremal Paths in Continuously Monitored Qubits
Philippe Lewalle, Areeya Chantasri, Andrew N. Jordan
We examine most-likely paths between initial and final states for diffusive quantum trajectories in continuously monitored pure-state qubits, obtained as extrema of a stochastic pa…
Quantum caustics in resonance fluorescence trajectories
M. Naghiloo, D. Tan, P. M. Harrington +3
We employ phase-sensitive amplification to perform homodyne detection of the resonance fluorescence from a driven superconducting artificial atom. Entanglement between the emitter…
Exotic Looped Trajectories of Photons in Three-Slit Interference
Omar S. Magana-Loaiza, Israel De Leon, Mohammad Mirhosseini +8
The validity of the superposition principle and of Born's rule are well-accepted tenants of quantum mechanics. Surprisingly, it has recently been predicted that the intensity patte…
Arrow of Time for Continuous Quantum Measurement
Justin Dressel, Areeya Chantasri, Andrew N. Jordan +1
We investigate the statistical arrow of time for a quantum system being monitored by a sequence of measurements. For a continuous qubit measurement example, we demonstrate that tim…
Engineering the Frequency Spectrum of Bright Squeezed Vacuum via Group Velocity Dispersion in an SU(1,1) Interferometer
Samuel Lemieux, Mathieu Manceau, Polina R. Sharapova +4
Bright squeezed vacuum, a promising tool for quantum information, can be generated by high-gain parametric down-conversion. However, its frequency and angular spectra are typically…
Center-of-mass interpretation for bipartite purity analysis of -party entanglement
Miguel A. Alonso, Xiao-Feng Qian, J. H. Eberly
We provide a graphical description of the entanglement of pure-state multiparty systems based on an analogy between a bipartite purity analysis and the centroid of a collection of…
High-dimensional quantum cloning and applications to quantum hacking
Frédéric Bouchard, Robert Fickler, Robert W Boyd +1
Attempts at cloning a quantum system result in the introduction of imperfections in the state of the copies. This is a consequence of the no-cloning theorem, which is a fundamental…
Overcoming experimental limitations in a non-linear two-qubit gate through postselection
Julián Martínez-Rincón
We introduce a modular-value two-qubit gate and explore its advantages in experimentally-limited situations. The gate is defined such that the final state of a target qubit is full…
Coherence Constraints and the Last Hidden Optical Coherence
Xiao-Feng Qian, Tanya Malhotra, A. Nick Vamivakas +1
We have discovered a new domain of optical coherence, and show that it is the third and last member of a previously unreported fundamental triad of coherences. These are unified by…
Rapid estimation of drifting parameters in continuously measured quantum systems
Luis Cortez, Areeya Chantasri, Luis Pedro García-Pintos +2
We investigate the determination of a Hamiltonian parameter in a quantum system undergoing continuous measurement. We demonstrate a computationally rapid yet statistically optimal…
Optimal adaptive control for quantum metrology with time-dependent Hamiltonians
Shengshi Pang, Andrew N. Jordan
Quantum metrology has been studied for a wide range of systems with time-independent Hamiltonians. For systems with time-dependent Hamiltonians, however, due to the complexity of d…
Entanglement in the Born-Oppenheimer Approximation
Artur F. Izmaylov, Ignacio Franco
The role of electron-nuclear entanglement on the validity of the Born-Oppenheimer (BO) approximation is investigated. While nonadiabatic couplings generally lead to entanglement an…
