Abstract

The possibility of generating light in a squeezed quantum state during saturated light amplification in a semiconductor amplifier is theoretically analyzed. Due to four-wave mixing process during amplification, weak components of the spontaneous emission of the medium with symmetric frequency shifts relative to the strong amplified wave acquire the quantum properties of two-mode squeezed light. The squeezing of quadrature components occurs in the range of frequency shifts of several GHz ($\sim$ the inverse relaxation time of the charge carrier density) and can reach 10 dB or more under optimal conditions. The formation of a two-mode squeezing phase facilitates the observation of the squeezing effect, in which a strong wave, playing the role of a local wave, exhibits quadrature noise suppression without additional homodyne detection.

Wigner Time: a data-oriented approach to experimental timeline creation for quantum science and technology

Precisely timed, multi-device control in atomic, molecular and optical physics is provided by specialized real-time systems, which impose their own terms on the description of the experiment: a program over a global clock, in which every stage boundary is an absolute time computed from everything preceding it. Such descriptions are tightly coupled -- changing one stage affects all later ones -- and are correspondingly hard to reuse, inspect, or move elsewhere. We introduce Wigner Time, a Python package in which the experimental procedure is instead represented as data: a table of timed updates, assembled by composing functions and referred to named points in the experiment rather than to absolute instants. Hardware enters only at a final conversion step, leaving the description readable and back-end agnostic. Wigner Time has run two cold-atom setups for more than two years, where replacing a hand-written real-time program improved the achievable temporal resolution five-fold; the design applies to any domain requiring precise multi-device timing.

The Concept of Entropic Time: A Preliminary Discussion

The deep connection between entropy and information is discussed in terms of both classical and quantum physics. The mechanism of information transfer between systems via entanglement is explored in the context of decoherence theory. The concept of entropic time is then introduced on the basis of information acquisition, which is argued to be effectively irreversible and consistent with both the Second Law of Thermodynamics and our psychological perception of time. This is distinguished from the notion of parametric time, which serves as the temporal parameter for the unitary evolution of a physical state in non-relativistic quantum mechanics. The interpretation of these ideas in terms of both subjective and objective collapse models is also discussed. It is shown that energy is conserved under subjective collapse schemes whereas, in general, under objective collapse it is not. This is consistent with the fact that the latter is inherently non-unitary and that energy conservation arises out of time symmetry in the first place.

Contextuality analysis of disturbing data cannot preserve core Kochen-Specker principles

We address the challenge of extending the criterion for Kochen-Specker contextuality to data with disturbance, to accommodate experimental imperfections or applications to macroscopic settings beyond quantum physics. We find that any such extension must abandon one or more principles that are core to the concept of contextuality. Specifically, we prove that no extended criterion agreeing with Kochen-Specker contextuality in the absence of disturbance can simultaneously satisfy the following: (1) any deterministic system is noncontextual; (2) discarding information cannot turn a noncontextual system into a contextual one; (3) classical post-processing cannot create contextuality; and (4) the joint realization of two statistically independent noncontextual systems is noncontextual. From the standpoint of resource theories, the obstruction arises because free operations can turn noncontextual disturbing behaviors into contextual non-disturbing ones. We suggest that future work on extended contextuality needs to move beyond the standard model-independent framework and account for the causal structure responsible for disturbance.
