Asymmetrical Crystal Qubit Structure

Quantum breakthrough: Scientists extend Qubit’s lifespan

Scientists have shown that they can extend the life of a molecular qubit by changing the structure of the surrounding crystal to be less symmetrical. The asymmetry shields the qubit from noise, allowing it to retain information five times longer than if it were housed in a symmetrical structure. Credit: MIT/Dan Laorenza Stability in asymmetry …

Physicist Sabine Hossenfelder: “There are quite a few areas where physics merges with religion”

Sabine Hossenfelder is a German theoretical physicist who writes books and runs a YouTube channel (with 618,000 subscribers at the time of writing) called Science Without the Gobbledygook. Born in Frankfurt, she studied mathematics at Goethe Universität and later focused on particle physics. His PhD explored the possibility of the Large Hadron Collider producing microscopic …

A particle accelerator that just ignited could reveal rare forms of matter

A particle accelerator that just ignited could reveal rare forms of matter

A few hundred yards from where we are sitting is a large metal chamber devoid of air and covered with the cables needed to control the instruments within. A particle beam silently passes through the interior of the chamber at about half the speed of light until it strikes a piece of solid material, resulting …

First collisions of lead ions in the Large Hadron Collider at record energy

First collisions of lead ions in the Large Hadron Collider at record energy

Event displays of the first Pb-Pb collision of Run3 taken on November 18, 2022. Credit: CERN On Friday, November 18, a test using lead ion collisions was performed in the Large Hadron Collider (LHC) and allowed experiments to validate new detectors and data processing systems before lead-lead physics next year. Course. After the successful start …

Evidence for Higgs boson contributions to the production of Z boson pairs at high energies

Evidence for Higgs boson contributions to the production of Z boson pairs at high energies

Left: Two-parameter probability sweep of off-shell production signal intensity parameters gg and EW, 𝜇off-shellF and 𝜇off-shellV, respectively. Dotted and dashed contours enclose the 68% (−2Δln𝐿=2.30) and 95% (−2Δln𝐿=5.99) CL regions. The cross marks the minimum and the blue diamond marks the SM hold. The integrated luminosity only reaches 138 fb-1 because 4ℓ on-hull events are …

Micro Ring Resonator

New measurements provide a glimpse into the quantum future

The micro-ring resonator, shown here as a closed loop, generated high-dimensional photon pairs. The researchers examined these photons by manipulating the phases of different frequencies, or colors, of light and mixing frequencies, as shown by the criss-crossing multicolored lines. Credit: Yun-Yi Pai/ORNL, US Department of Energy A multi-institutional team has created an efficient method to …
