Shifting Colors for On-Chip Photonics To Power Next Generation Quantum Computers and Networks

On-chip frequency shifters in the gigahertz range could be used in next generation quantum computers and networks.

The ability to precisely control and change properties of a photon, including polarization, position in space, and arrival time, gave rise to a wide range of communication technologies we use today, including the Internet. The next generation of photonic technologies, such as photonic quantum networks and computers, will require even more control over the properties of a photon.

One of the hardest properties to change is a photon’s color, otherwise known as its frequency, because changing the frequency of a photon means changing its energy.

New Platform for Quantum Computing? Artificial Material Mimics Quantum Entangled Rare Earth Compounds

Physicists have created a new ultra-thin two-layer material with quantum properties that normally require rare earth compounds. This material, which is relatively easy to make and does not contain rare earth metals, could provide a new platform for quantum computing and advance research into unconventional superconductivity and quantum criticality.

The researchers showed that by starting from seemingly common materials, a radically new quantum state of matter can appear. The discovery emerged from their efforts to create a quantum spin liquid which they could use to investigate emergent quantum phenomena such as gauge theory. This involves fabricating a single layer of atomically thin tantalum disulfide, but the process also creates islands that consist of two layers.

MX Linux has Released a New Edition for Newer Hardware

MX Linux 21 AHS is finally available with Linux Kernel 5.14 and updated open-source graphics stack. But, is it for everyone?

MX Linux 21 was officially unveiled last month while introducing a new Fluxbox edition. However, the Advanced Hardware Support (AHS) ISO was not a part of it.

Recently, MX Linux announced the availability of MX Linux 21 AHS and a new AHS repo for existing MX Linux 21 users.

In this article, let us explore more about it.

How molecular clusters in the nucleus interact with chromosomes

A cell stores all of its genetic material in its nucleus, in the form of chromosomes, but that’s not all that’s tucked away in there. The nucleus is also home to small bodies called nucleoli — clusters of proteins and RNA that help build ribosomes.

Using computer simulations, MIT chemists have now discovered how these bodies interact with chromosomes in the nucleus, and how those interactions help the nucleoli exist as stable droplets within the nucleus.

Their findings also suggest that chromatin-nuclear body interactions lead the genome to take on a gel-like structure, which helps to promote stable interactions between the genome and transcription machineries. These interactions help control gene expression.

NVIDIA CMP 170HX mining card with GA100 GPU has a massive heatspreader

Due to the very limited availability and the high price of this card, there are not actually that many pictures of CMP 170HX on the Internet. Fortunately, Linus was brave enough to take a look under the card’s hood. As it turns out, the GPU has a very large heat spreader completetly covering the whole interposer area.

One of the hardest properties to change is a photon’s color, otherwise known as its frequency, because changing the frequency of a photon means changing its energy.

Today, most frequency shifters are either too inefficient, losing a lot of light in the , or they can’t convert light in the gigahertz range, which is where the most important frequencies for communications, computing, and other applications are found.
