Quantum simulation of thermodynamics in an integrated quantum photonic processor

The emergence of relaxation in unitarily evolving systems can be seen as a paradox, but not once the distinction between local and global dynamics is considered. Here, the authors use photons in an integrated optical interferometer to show that, for a system evolving unitarily on a global level, single-mode measurements converge to those of a thermal state.

Comparison of temperature and doping dependence of elastoresistivity near a putative nematic quantum critical point

Evidence for quantum criticality in Fe-based superconductors is still being accumulated. Here, the authors observe power-law behavior of the elastoresistivity as a function of composition in Ba(Fe_1−xCo_x)₂As₂ near a putative nematic quantum critical point, consistent with expectations for quantum criticality, while the temperature dependence near the critical doping deviates from a power law.

Nonequilibrium charge-density-wave order beyond the thermal limit

Photo-induced phase transitions triggered by an ultrafast excitation cannot be described within the quasi-equilibrium framework. Here, using time-resolved experimental probes, the authors report a transient charge-density-wave order in TbTe₃ and describe it using a model with a non-equilibrium transition temperature.

Tomography of quantum detectors

In quantum mechanics, measurement has a fundamentally different role than in classical physics. Now a general method has been devised to characterize a quantum measurement device, completing the suite of so-called tomography techniques required to fully specify an experiment.

Experimental quantum-enhanced estimation of a lossy phase shift

Evidence that appropriately engineered quantum states outperform both standard and N00N states in the precision of phase estimation — even in the presence of losses and decoherence — is presented. The results show that the strategy for realizing the quantum enhancement of metrology is quite distinct from protecting quantum information encoded in light.

Broadband single-photon-level memory in a hollow-core photonic crystal fibre

An optical memory is demonstrated in a kagome photonic crystal fibre whose 26-μm-diameter hollow core is loaded with cesium atoms. Gigahertz-bandwidth light is stored using a far-detuned Raman interaction. It has a memory efficiency is 27 ± 1% and a signal-to-noise ratio of 2.6:1 — the highest at the single-photon level of any memory at room temperature.

Towards high-speed optical quantum memories

Quantum memories for storing and releasing photons are required for quantum computers and quantum communications. So far, their operational bandwidths have limited data-rates to megahertz. Researchers now demonstrate coherent storage and retrieval of subnanosecond low-intensity light pulses with spectral bandwidths exceeding 1 GHz.

Macroscopic non-classical states and terahertz quantum processing in room-temperature diamond

Researchers investigate the optical phonon modes of bulk diamond at room temperature. Ultrafast Raman scattering measurements show an extended and highly non-classical state in the optical phonon modes of bulk diamond. The researchers also demonstrate a terahertz-bandwidth quantum memory based on transient ultrafast Raman scattering from the optical phonons.
