Search via Quantum Walks
Abstract: Randomization of quantum states is the quantum analogue of the classical one-time pad. We present an improved, efficient construction of an approximately randomizing map that uses O( d /eps...

Quantum Journal Club: Quantum Discord Cannot Be Shared
Abstract: Bohr proposed that the outcome of a measurement becomes objective and real, and, hence, classical, when its results can be communicated by classical means. In this work we revisit Bohr’s p...

Quantum simulations with strongly interacting photons: Simulating exotic phases of matter and applications in quantum technology
Abstract: Classical computers require enormous computing power and memory to simulate even the most modest quantum systems. That makes it difficult to model, for example, why certain materials are in...

Multiplexing continuous-variable quantum information in optics
Abstract: Recently, very large entangled states of light have been generated using multiplexing techniques. I will explore some experiments that have successfully shown multiplexing to be a viable ap...

Quantum Journal Club: Repeated quantum error correction on a continuously encoded qubit by real-time feedback
Abstract: Reliable quantum information processing in the face of errors is a major fundamental and technological challenge. Quantum error correction protects quantum states by encoding a logical quan...
