Gaussian quantum information [PDF]

open access: yesReviews of Modern Physics, 2012
The science of quantum information has arisen over the last two decades centered on the manipulation of individual quanta of information, known as quantum bits or qubits. Quantum computers, quantum cryptography and quantum teleportation are among the most celebrated ideas that have emerged from this new field.

Persistence of quantum information [PDF]

open access: yesPhysics 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]

open access: yesPhysical 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]

open access: yesFoundations 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 ...

Experimental demonstration of coherence flow in PT- and anti-PT-symmetric systems

open access: yesCommunications Physics, 2021
The gain and loss inherent in non-Hermitian quantum systems can modify the flow of coherence between subsystems, which may be lost or recovered from the environment.

Experimental unsupervised learning of non-Hermitian knotted phases with solid-state spins

open access: yesnpj Quantum Information, 2022
Non-Hermiticity has widespread applications in quantum physics. It brings about distinct topological phases without Hermitian counterparts, and gives rise to the fundamental challenge of phase classification. Here, we report an experimental demonstration

Coherent memory for microwave photons based on long-lived mechanical excitations

open access: yesnpj Quantum Information, 2023
Mechanical resonators, due to their capability to host ultralong-lived phonon modes, are particularly attractive for quantum state storage and as memory elements in conjunction with quantum computing and communication networks.
