Quantum information to the home [PDF]
New Journal of Physics, 2011 Information encoded on individual quanta will play an important role in our future lives, much as classically encoded digital information does today. Combining quantum information carried by single photons with classical signals encoded on strong laser ...

The multifarious quantum information
Quantum Information Processing, 2006 This paper considers the scope and possibilities of quantum information within the consensus interpretation of the theory. It is pointed out that a prepared quantum state offers a multitude of answers determined by the query directed to it.

Quantum information effects [PDF]
Proceedings of the ACM on Programming Languages, 2022 We study the two dual quantum information effects to manipulate the amount of information in quantum computation: hiding and allocation. The resulting type-and-effect system is fully expressive for irreversible quantum computing, including measurement.

Quantum Information Scrambling in Non-Markovian Open Quantum System. [PDF]
Entropy (Basel), 2022 In this paper, we investigate the dynamics of a spin chain whose two end spins interact with two independent non-Markovian baths by using the non-Markovian quantum state diffusion (QSD) equation approach.

Towards practical quantum computers: transmon qubit with a lifetime approaching 0.5 milliseconds
npj Quantum Information, 2022 Here we report a breakthrough in the fabrication of a long lifetime transmon qubit. We use tantalum films as the base superconductor. By using a dry etching process, we obtained transmon qubits with a best T 1 lifetime of 503 μs. As a comparison, we also
