Implementing generalized measurements with superconducting qubits
Justin Dressel, Todd A. Brun, Alexander N. Korotkov
We describe a method to perform any generalized purity-preserving measurement of a qubit with techniques tailored to superconducting systems. First, we consider two methods for rea…
Avoiding Loopholes with Hybrid Bell-Leggett-Garg Inequalities
Justin Dressel, Alexander N. Korotkov
By combining the postulates of macrorealism with Bell locality, we derive a qualitatively different hybrid inequality that avoids two loopholes that commonly appear in Leggett-Garg…
Certainty in Heisenberg's uncertainty principle: Revisiting definitions for estimation errors and disturbance
Justin Dressel, Franco Nori
We revisit the definitions of error and disturbance recently used in error-disturbance inequalities derived by Ozawa and others by expressing them in the reduced system space. The…
Classical Field Approach to Quantum Weak Measurements
Justin Dressel, Konstantin Y. Bliokh, Franco Nori
By generalizing the quantum weak measurement protocol to the case of quantum fields, we show that weak measurements probe an effective classical background field that describes the…
Quantum instruments as a foundation for both states and observables
Justin Dressel, Andrew N. Jordan
We demonstrate that quantum instruments can provide a unified operational foundation for quantum theory. Since these instruments directly correspond to laboratory devices, this fou…
Colloquium: Understanding Quantum Weak Values: Basics and Applications
Justin Dressel, Mehul Malik, Filippo M. Miatto +2
Since its introduction 25 years ago, the quantum weak value has gradually transitioned from a theoretical curiosity to a practical laboratory tool. While its utility is apparent in…
