Four single-photon states are generated and entangled on a single micrometre-scale silicon chip, and provide the basis for the demonstration of chip-to-chip quantum teleportation.
Experiments demonstrate quantum phase sensing with a four-mode entangled state, reaching a measurement precision that is beyond what can be achieved by separate individual probes.
The microscopic quantum Hall edge currents and the equilibrium currents that generate the mirror magnetic monopoles in time-reversal-symmetry-broken topological matter are directly imaged in the quantum Hall state in graphene by using a SQUID-on-tip.
Single-cycle interferometric autocorrelation measurements of electrons tunnelling across the gap of a plasmonic bowtie antenna and quantitative models provide insight into the physical interactions that drive the electron transfer.
Transport measurements show that nematic fluctuations near a phase transition increase the temperature at which superconductivity occurs by a factor of nearly six. This happens in a non-magnetic nickel-based compound.
Applying pressure to a cuprate reveals that the strange metal phase has a two-dimensional character, as shown by emerging Berezinskii–Kosterlitz–Thouless behaviour.
Continuous-variables quantum information processing requires non-Gaussian states and operations. The generation of non-Gaussian quantum states of a multimode field is now reported through a mode-selective photon-subtraction scheme
The authors use spin waves to demonstrate that charged quantum Hall skyrmions exist away from integer filling. They also see evidence of several fractional skyrmion states.
Planets are assembled from the ground up, beginning with millimetre-sized interstellar dust grains. Microgravity experiments suggest that centimetre-sized dust aggregates form from these smaller grains via collisional charging.
In our understanding of planetary formation, it is still unclear how millimetre-sized dust grains grow into centimetre-sized aggregates. Microgravity experiments now show that electrical charging of the grains leads to the formation of larger clumps.
High-magnetic-field experiments on the recently discovered unconventional superconductor UTe2 are consistent with p-wave pairing arising while time-reversal symmetry is broken. In turn, this suggests that this material is a candidate for a chiral superconductor that may be exploited for topological quantum computing.
