Detecting crosstalk errors in quantum information processors [PDF]
Quantum, 2019 Crosstalk occurs in most quantum computing systems with more than one qubit. It can cause a variety of correlated and nonlocal crosstalk errors that can be especially harmful to fault-tolerant quantum error correction, which generally relies on errors ...

Unlearning quantum information [PDF]
The European Physical Journal D, 2014 Quantum dynamics can be driven by measurement. By constructing measurements that gain no information, effective unitary evolution can be induced on a quantum system, for example in ancilla driven quantum computation. In the non-ideal case where a measurement does reveal some information about the system, it may be possible to "unlearn" this information

Quantum Control and Quantum Information Technology [PDF]
The Scientific World Journal, 2013 Quantum information technology has been recognized as one of the most promising future technologies (e.g., see [1]). The development of quantum control theory is a key task for practical quantum information technology (e.g., see [2–4]. Recent advances in quantum information technologies and robust quantum information processing require the dynamics of ...

Quantum information processing with space-division multiplexing optical fibres [PDF]
Communications Physics, 2019 The optical fibre is an essential tool for our communication infrastructure since it is the main transmission channel for optical communications. The latest major advance in optical fibre technology is space-division multiplexing, where new fibre designs

Noiseless photonic non-reciprocity via optically-induced magnetization
Nature Communications, 2021 Optical nonreciprocity through magneto-optical effects requires bulky apparatuses and strong magnetic fields, while magnetic-free approaches are difficult to implement. Here, the authors use optically-induced magnetisation in an atomic ensemble to get 50

Alternative new notation for quantum information theory [PDF]
International Journal of Theoretical Physics 2007, 2003 A new notation has been introduced for the quantum information theory. By this notation,some calculations became simple in quantum information theory such as quantum swapping, quantum teleportation.

npj Quantum Information, 2023 Entanglement distribution is at the heart of most quantum communication protocols. Inevitable loss of photons along quantum channels is a major obstacle for distributing entangled photons over long distances, as the no-cloning theorem forbids the ...
