Quantum Journal Club: Speed Optimized Two-Qubit Gates with Laser Coherent Contro
Abstract: We propose a new concept for a two-qubit gate operating on a pair of trapped ions based on laser coherent control techniques. The gate is insensitive to the temperature of the ions, works a...

Quantum Journal Club: Generation of spin-motion entanglement in a trapped ion us
Abstract: Applying a magnetic eld gradient to a trapped ion allows long-wavelength microwave radiation to produce a mechanical force on the ion's motion when internal transitions are driven. We demon...

QUIC talk: Cryptographic Reversibility
Abstract: In this talk we consider the problem of cryptographic reversibility, which asks when a tripartite distribution PXYZ can be asymptotically distilled into secret key and diluted back into PXY...

Quantum group seminar:Beyond the diffraction limit in optical microscopy and lit
Abstract: In optical microscopy and lithography, the resolution is restricted to about half the wavelength of the light by something called the diffraction limit. Many attempts have been made to adva...

Soft Decoding of A Quantum Measurement Apparatus
Abstract: Quantum measurements are commonly performed by thresholding a collection of analog detector-output signals to obtain a sequence of single-shot bit values. The intrinsic irreversibility of t...
