Entanglement Sharing Protocol via Quantum Error Correcting Codes
Ran Hee Choi, Ben Fortescue, Gilad Gour +1
We introduce a new multiparty cryptographic protocol, which we call `entanglement sharing schemes', wherein a dealer retains half of a maximally-entangled bipartite state and encod…
Exact synthesis of multiqubit Clifford+T circuits
Brett Giles, Peter Selinger
We prove that a unitary matrix has an exact representation over the Clifford+T gate set with local ancillas if and only if its entries are in the ring Z[1/sqrt(2),i]. Moreover, we…
Controlling and reversing the transition from classical diffusive to quantum ballistic transport in a quantum walk by driving the coin
Peng Xue, Barry C. Sanders
We show that the standard quantum-walk quantum-to-classical transition, characterized by ballistic-to-diffusive spreading of the walker's position, can be controlled by externally…
Optimal Storage and Retrieval of Single-Photon Waveforms
Shuyu Zhou, Shanchao Zhang, Chang Liu +5
We report an experimental demonstration of optimal storage and retrieval of heralded single-photon wave packets using electromagnetically induced transparency (EIT) in cold atoms a…
Macroscopic superpositions via nested interferometry: finite temperature and decoherence considerations
Brian Pepper, Evan Jeffrey, Roohollah Ghobadi +2
Recently there has been much interest in optomechanical devices for the production of macroscopic quantum states. Here we focus on a proposed scheme for achieving macroscopic super…
Simulating Symmetric Time Evolution With Local Operations
Borzu Toloui, Gilad Gour
In closed systems, dynamical symmetries lead to conservation laws. However, conservation laws are not applicable to open systems that undergo irreversible transformations. More gen…
