Small Unextendible Sets of MUBs
Abstract: In quantum information, Mutually Unbiased Bases (MUBs) correspond to sets of pairwise complementary observables. The maximal number of such bases in a system of dimension d is d+1, and cons...

Quantum optics with cold atomic gases
Abstract: Ultra-cold atomic gases can now be precisely controlled and manipulated in the quantum regime. In this talk, I will present our results on using ensembles of cold atoms, especially high-lyi...

Optical levitation and quantum spin-optomechanics of levitated nanodiamonds
Abstract: Optomechanical systems, such as LIGO (Laser Interferometer Gravitational-Wave Observatory), are extremely sensitive devices that have broad applications. Once cooled to the quantum regime, ...

Quantum Journal Club：A universal gate for fixed-frequency qubits via a tunable bus
Abstract: Claude Shannon proved in 1949 that information-theoretic-secure encryption is possible if the encryption key is used only once, is random, and is at least as long as the message itself. Not...

Quantum Journal Club: Experimental loophole-free violation of a Bell inequality using entangled electron spins separated by 1.3 km
Abstract: For more than 80 years, the counterintuitive predictions of quantum theory have stimulated debate about the nature of reality. In his seminal work, John Bell proved that no theory of nature...
