    2 days ago · The consequences of quantum decoherence in systems can lead to significant implications for the behavior and predictability of quantum phenomena. Quantum coherence breakdown and information loss are primary outcomes of decoherence. When a quantum system interacts with its environment, coherence is disrupted, causing the system to lose its ...

  2. 2 days ago · And because a qubit, unlike a bit, can change continuously, precisely controlling a qubit is a further challenge, even when decoherence is in check. While theorists may find it convenient to regard a qubit (or a bit) as an abstract object, in an actual processor a qubit needs to be encoded in a particular physical system.

  3. 4 days ago · By simulating fake people while interacting with popular smart voice assistants, such as Amazon’s Alexa, Google Assistant and Apple’s Siri, researchers have uncovered the different approaches...

  4. 3 days ago · The ordered atomic array emerges as a versatile atom-photon interface for exquisite control of light-matter interaction at the nanoscale. In particular, the one-dimensional atom-waveguide system can achieve strong coupling between a single atom and a photon, where two atomic mirrors coupled to waveguide act as a high-finesse cavity. In this work we show that under the strong-coupling regime, the mirror atoms arranged in the form of a Su-Schrieffer-Heeger chain are advantageous in decoherence ...

  6. 3 days ago · Measurements remain as an interesting topic of research since the formulation of quantum theory. Attempts to model quantum measurements by unitary processes are prone to various foundational issues. Here, it is proposed that measurement devices can be modelled to have an open decoherence dynamics that is faster than any other relevant timescale, which is referred to as the ultradecoherence limit. In this limit, it is shown that the clicking rate of measurement devices can be derived from its ...
