Abstract: At sufficiently low temperatures, condensed-matter systems tend to develop order. An notable exception to this behavior is quantum spin-liquids, where fluctuations prevent transition to an ...
Abstract: We propose a new quantum key distribution protocol in which information is encoded on continuous variables of a single photon. In this protocol, Alice randomly encodes her information on ei...
Abstract: We propose an efficient protocol to perform universal quantum control of an oscillator mode (e.g. cavity mode) off-resonantly coupled to an ancillary qubit. With an excitation number trunca...
Abstract: Quantum technology is a revolutionary idea to change the paradigm of modern technology using quantum states and operations of physical systems. An ability to manipulate a quantum state is a...
Abstract: Control over physical systems at the quantum level is important in fields as diverse as metrology, information processing, simulation and chemistry. For trapped atomic ions, the quantized m...
Abstract: The relation between projective measurements and generalized quantum measurements is a fundamental problem in quantum physics, and clarifying this issue is also important to quantum technol...
