A dual-species Rydberg array

Posted by in categories: computing, particle physics, quantum physics

In quantum computing, scientists often work with arrays of atoms called Rydberg atom arrays, which allow them to simulate quantum systems and perform computations.


Rydberg atoms in optical tweezers are a promising platform for quantum information science. A platform composed of dual-species Rydberg arrays has been realized, offering access to unexplored interaction regimes and crosstalk-free midcircuit control.

Thermal effects in spintronics systematically assessed for first time

Posted by in categories: computing, particle physics

Spintronics—devices that use microscopic magnetism in conjunction with electric current—could lead to computing technology as fast as conventional electronics but much more energy efficient. As such devices are developed and studied, an important unresolved question is how device operation is affected by heating.

Phase transition in magic with random quantum circuits

Posted by in categories: computing, quantum physics

In quantum computing, “magic” refers to a special quality of quantum states that is essential for enabling powerful, fault-tolerant quantum computations.


Coherent noise affecting a random error correcting code is now shown to produce aion between phases that accumulate and destroy magic.

Samsung is creating the world’s first Petabyte SSD

Posted by in categories: computing, transportation

While most of us are still struggling to find SSDs with greater capacities than 4TB, Samsung is working on creating the world’s first petabyte SSD. At least, that’s their plan. Last year, reports suggested that the company was about a decade away. Now, they seem much closer.

As the world’s largest manufacturer of 3D NAND storage, they’re certainly one of the most likely to do it. Samsung has revealed more information about its planes, and how it’s working to get to that 1,000-layer NAND required for such high capacities.

Samsung has long been a leader in large capacity solid state drives. And while they’re not readily available to the average consumer due to their (still) prohibitively expensive prices, Samsung announced a 16TB SSD way back in 2015.

Silicon Chip Propels 6G Communications Forward

Posted by in categories: computing, internet

A team of scientists has unlocked the potential of 6G communications with a new polarization multiplexer. Terahertz communications represent the next frontier in wireless technology, promising data transmission rates far exceeding current systems.

By operating at terahertz frequencies, these systems can support unprecedented bandwidth, enabling ultra-fast wireless communication and data transfer. However, one of the significant challenges in terahertz communications is effectively managing and utilizing the available spectrum.

The team has developed the first ultra-wideband integrated terahertz polarization (de)multiplexer implemented on a substrateless silicon base which they have successfully tested in the sub-terahertz J-band (220–330 GHz) for 6G communications and beyond.

Researchers observe an antiferromagnetic diode effect in even-layered MnBi₂Te₄

Posted by in categories: computing, particle physics

Antiferromagnets are materials in which the magnetic moments of neighboring atoms are aligned in an alternating pattern, resulting in no net macroscopic magnetism. These materials have interesting properties that could be favorable for the development of spintronic and electronic devices.

Three Mile Island reactor to provide power for Microsoft data centers

Posted by in categories: climatology, computing, nuclear energy, sustainability

HARRISBURG, Pa. — The owner of the shuttered Three Mile Island nuclear power plant said Friday that it plans to restart the reactor under a 20-year agreement that calls for tech giant Microsoft to buy the power to supply its data centers with carbon-free energy.

The announcement by Constellation Energy comes five years after its then-parent company, Exelon, shut down the plant, saying it was losing money and that Pennsylvania lawmakers had refused to bail it out.

Bio-inspired wick enhances electronic chip cooling

Posted by in categories: computing, cyborgs, transhumanism

A research team led by Prof. Ye Hong from the University of Science and Technology of China has developed an alumina ceramic bionic wick with finger-like pores inspired by the stomatal array of natural leaves. Their research is published in Langmuir.

As the performance of electronic chips continues to improve, their also increases, posing new challenges for cooling strategies. Loop heat pipes (LHPs) are a compelling cooling solution due to their high heat transfer capability, antigravity heat transfer, and absence of moving parts.

However, the differing requirements for flow resistance and capillary force make designing the structure of the capillary wick within an LHP challenging. Specifically, larger pores are needed for gaseous working fluids to reduce flow resistance, while smaller pores are necessary to provide sufficient capillary force for liquid suction.
