Adaptive quantum state tomography improves accuracy quadratically
D. H. Mahler, Lee A. Rozema, Ardavan Darabi +3
We introduce a simple protocol for adaptive quantum state tomography, which reduces the worst-case infidelity between the estimate and the true state from to $O(N^{-1…
Violation of Heisenberg's Measurement-Disturbance Relationship by Weak Measurements
Lee A. Rozema, Ardavan Darabi, Dylan H. Mahler +3
While there is a rigorously proven relationship about uncertainties intrinsic to any quantum system, often referred to as "Heisenberg's Uncertainty Principle," Heisenberg originall…
Identification of Decoherence-Free Subspaces Without Quantum Process Tomography
D. H. Mahler, L. Rozema, A. Darabi +1
Characterizing a quantum process is the critical first step towards applying such a process in a quantum information protocol. Full process characterization is known to be extremel…
Self-calibrating Quantum State Tomography
Agata M. Branczyk, Dylan H. Mahler, Lee A. Rozema +3
We introduce and experimentally demonstrate a technique for performing quantum state tomography on multiple-qubit states despite incomplete knowledge about the unitary operations u…
A reply to "Problems with modelling closed timelike curves as post-selected teleportation"
Seth Lloyd, Lorenzo Maccone, Raul Garcia-Patron +8
In arXiv:1107.4675 Ralph uses our post-selection model of closed timelike curves (P-CTC) to construct an "unproven-theorem" paradox, and claims that this voids our argument that P-…
Closed timelike curves via post-selection: theory and experimental demonstration
Seth Lloyd, Lorenzo Maccone, Raul Garcia-Patron +8
Closed timelike curves (CTCs) are trajectories in spacetime that effectively travel backwards in time: a test particle following a CTC can in principle interact with its former sel…
