Heisenberg-limited metrology with information recycling

Simon A. Haine, Stuart S. Szigeti, Matthias D. Lang +1

Information recycling has been shown to improve the sensitivity of atom interferometers by exploiting atom-light entanglement. In this paper, we apply information recycling to an i…

Robust quantum logic in neutral atoms via adiabatic Rydberg dressing

Tyler Keating, Robert L. Cook, Aaron Hankin +3

We study a scheme for implementing a controlled-Z (CZ) gate between two neutral-atom qubits based on the Rydberg blockade mechanism in a manner that is robust to errors caused by a…

Rapid readout of a register of qubits using open loop quantum control

Joshua Combes, Aaron Denney, Howard M. Wiseman

Measurements are a primitive for characterizing quantum systems. Reducing the time taken to perform a measurement may be beneficial in many areas of quantum information processing.…

Weak-value amplification: state of play

George C. Knee, Joshua Combes, Christopher Ferrie +1

Weak values arise in quantum theory when the result of a weak measurement is conditioned on a subsequent strong measurement. The majority of the trials are discarded, leaving only…

Quantum Bochner's theorem for phase spaces built on projective representations

Ninnat Dangniam, Christopher Ferrie

Bochner's theorem gives the necessary and sufficient conditions on a function such that its Fourier transform corresponds to a true probability density function. In the Wigner phas…

Resource quality of a symmetry-protected topologically ordered phase for quantum computation

Jacob Miller, Akimasa Miyake

We investigate entanglement naturally present in the 1D topologically ordered phase protected with the on-site symmetry group of an octahedron as a potential resource for teleporta…

Robust and efficient in situ quantum control

Christopher Ferrie, Osama Moussa

Precision control of quantum systems is the driving force for both quantum technology and the probing of physics at the quantum and nano-scale. We propose an implementation indepen…

Fidelity-optimized quantum state estimation

Amir Kalev, Itay Hen

We describe an optimized, self-correcting procedure for the Bayesian inference of pure quantum states. By analyzing the history of measurement outcomes at each step, the procedure…

A new class of time-dependent Bell inequalities in Wigner form

N. Nikitin, V. Sotnikov, K. Toms

We derive a new class of time-dependent Bell inequalities in Wigner form under the assumption of locality in the framework of Kolmogorov's probability theory. We consider violation…

Single Shot Quantum State Estimation via a Continuous Measurement in the Strong Backaction Regime

Robert L. Cook, Carlos A. Riofrío, Ivan H. Deutsch

We study quantum tomography based on a stochastic continuous-time measurement record obtained from a probe field collectively interacting with an ensemble of identically prepared s…

Adiabatic topological quantum computing

Chris Cesare, Andrew J. Landahl, Dave Bacon +2

Topological quantum computing promises error-resistant quantum computation without active error correction. However, there is a worry that during the process of executing quantum g…

Self-guided quantum tomography

Christopher Ferrie

We introduce a self-learning tomographic technique in which the experiment guides itself to an estimate of its own state. Self-guided quantum tomography (SGQT) uses measurements to…

Optimal Quantum-Enhanced Interferometry

Matthias D. Lang, Carlton M. Caves

We analyze the ultimate bounds on the phase sensitivity of an interferometer, given the constraint that the state input to the interferometer's initial 50:50 beamsplitter is a…

Quantum Model Averaging

Christopher Ferrie

Standard tomographic analyses ignore model uncertainty. It is assumed that a given model generated the data and the task is to estimate the quantum state, or a subset of parameters…

Encoding secret information in measurement settings

Syed. M. Assad, Amir Kalev

Secure communication protocols are often formulated in a paradigm where the message is encoded in measurement outcomes. In this work we propose a rather unexplored framework in whi…

Characterization of control noise effects in optimal quantum unitary dynamics

David Hocker, Constantin Brif, Matthew D. Grace +5

This work develops measures for quantifying the effects of field noise upon targeted unitary transformations. Robustness to noise is assessed in the framework of the quantum contro…

Quantum process tomography of unitary and near-unitary maps

Charles H. Baldwin, Amir Kalev, Ivan H. Deutsch

We study quantum process tomography given the prior information that the map is a unitary or close to a unitary process. We show that a unitary map on a -level system is complet…

The best Fisher is upstream: data processing inequalities for quantum metrology

Christopher Ferrie

We apply the classical data processing inequality to quantum metrology to show that manipulating the classical information from a quantum measurement cannot aid in the estimation o…

Higher-order interference and single-system postulates characterizing quantum theory

Howard Barnum, Markus P. Mueller, Cozmin Ududec

We present a new characterization of quantum theory in terms of simple physical principles that is different from previous ones in two important respects: first, it only refers to…

How the result of a single coin toss can turn out to be 100 heads

Christopher Ferrie, Joshua Combes

We show that the phenomenon of anomalous weak values is not limited to quantum theory. In particular, we show that the same features occur in a simple model of a coin subject to a…

Mutually unbiased measurements in finite dimensions

Amir Kalev, Gilad Gour

We generalize the concept of mutually unbiased bases (MUB) to measurements which are not necessarily described by rank one projectors. As such, these measurements can be a useful t…
