Persistence of quantum information [PDF]
Physics Letters A, 2007 There is an increasing interest in the role of macroscopic environments to our understanding of the basics of quantum theory. The knowledge of the implications of the quantum theory to other theories, especially to the statistical mechanics and the domain of validity has captivated scientists from the beginning of quantum description. In such a context,

Types of quantum information [PDF]
Physical Review A, 2007 Quantum, in contrast to classical, information theory, allows for different incompatible types (or species) of information which cannot be combined with each other. Distinguishing these incompatible types is useful in understanding the role of the two classical bits in teleportation (or one bit in one-bit teleportation), for discussing decoherence in ...

Quantum Mechanics is About Quantum Information [PDF]
Foundations of Physics, 2005 I argue that quantum mechanics is fundamentally a theory about the representation and manipulation of information, not a theory about the mechanics of nonclassical waves or particles. The notion of quantum information is to be understood as a new physical primitive -- just as, following Einstein's special theory of relativity, a field is no longer ...

Quantum information with top quarks in QCD [PDF]
Quantum, 2022 Top quarks represent unique high-energy systems since their spin correlations can be measured, thus allowing to study fundamental aspects of quantum mechanics with qubits at high-energy colliders.

Engineered dissipation for quantum information science [PDF]
Nature Reviews Physics, 2022 Quantum information processing relies on the precise control of non-classical states in the presence of many uncontrolled environmental degrees of freedom.

Probing quantum information propagation with out-of-time-ordered correlators [PDF]
Nature Physics, 2021 Interacting many-body quantum systems show a rich array of physical phenomena and dynamical properties, but are notoriously difficult to study: they are analytically challenging and exponentially hard to simulate on classical computers.

Quantum reading of quantum information
Journal of Physics A: Mathematical and Theoretical, 2023 Abstract We extend the notion of quantum reading to the case where the information to be retrieved, which is encoded into a set of quantum channels, is of quantum nature. We use two-qubit unitaries describing the system-environment interaction, with the initial environment state determining the system’s input-output channel and hence the

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
