Intel unveils its second-generation quantum computing control chip

[email protected]_84

Intel unveiled its second-generation quantum computing control chip during its Intel Labs virtual event today. The chip, codenamed Horse Ridge II, is another milestone toward making quantum computing — one of the holy grails of computing — more practical. The new prototype builds on the first-generation Horse Ridge controller introduced in 2019. Horse Ridge II has more capability and higher levels of integration to control a quantum computer, which remains a long-term goal for the company.

At the outset of the project, Intel’s researchers designed the scalable system-on-chip (SOC) to operate at cryogenic temperatures, simplifying the control electronics and interconnects required to elegantly scale and operate large quantum computing systems. Most quantum computing systems only really works at near-freezing temperatures. Intel is trying to change that, but in the meantime, the control chip eliminates having to run hundreds of wires into a refrigerated case that houses the quantum computer.

Quantum nanodiamonds may help detect disease earlier — ScienceDaily

[email protected]_84

The quantum sensing abilities of nanodiamonds can be used to improve the sensitivity of paper-based diagnostic tests, potentially allowing for earlier detection of diseases such as HIV, according to a study led by UCL researchers in the i-sense McKendry group.

Paper-based lateral flow tests work the same way as a pregnancy test in that a strip of paper is soaked in a fluid sample and a change in colour — or fluorescent signal — indicates a positive result and the detection of virus proteins or DNA. They are widely used to detect viruses ranging from HIV to SARS-CoV-2 (lateral flow tests for Covid-19 are currently being piloted across England) and can provide a rapid diagnosis, as the results do not have to be processed in a lab.

The new research, published in Nature, found that low-cost nanodiamonds could be used to signal the presence of an HIV disease marker

Quantum magic squares cannot be as easily characterized as their ‘classical’ cousins — ScienceDaily

[email protected]_84

Magic squares belong to the imagination of humanity for a long time. The oldest known magic square comes from China and is over 2000 years old. One of the most famous magic squares can be found in Albrecht Dürer’s copper engraving Melencolia I. Another one is on the facade of the Sagrada Família in Barcelona. A magic square is a square of numbers such that every column and every row sums to the same number. For example, in the magic square of the Sagrada Família every row and column sums to 33.

If the magic square can contain real numbers, and every row and column sums to 1, then it is called a doubly stochastic matrix. One particular example would be a matrix that has 0’s everywhere except for one 1 in every column and every row. This is called a permutation matrix. A famous theorem says that every doubly

Direct visualization of quantum dots reveals shape of quantum wave function — ScienceDaily

[email protected]_84

Trapping and controlling electrons in bilayer graphene quantum dots yields a promising platform for quantum information technologies. Researchers at UC Santa Cruz have now achieved the first direct visualization of quantum dots in bilayer graphene, revealing the shape of the quantum wave function of the trapped electrons.

The results, published November 23 in Nano Letters, provide important fundamental knowledge needed to develop quantum information technologies based on bilayer graphene quantum dots.

“There has been a lot of work to develop this system for quantum information science, but we’ve been missing an understanding of what the electrons look like in these quantum dots,” said corresponding author Jairo Velasco Jr., assistant professor of physics at UC Santa Cruz.

While conventional digital technologies encode information in bits represented as either 0 or 1, a quantum bit, or qubit, can represent both states at the same time due to quantum superposition. In theory,

Led by academician Prof. Guo Guangcan from the Chinese Academy of Sciences (CAS), Prof. Li Chuanfeng’s group and Prof. Xiang Guoyong’s group from University of Science and Technology of China (USTC), CAS, in cooperation with theoretical physicists from Germany, Italy and Switzerland, conducted the first experiment using entangled collective measurement for minimizing quantum measurement backaction based on photonic system.


The result was published online in Physical Review Letters on Nov. 16.

When an observable object is measured twice on an evolving coherent quantum system, the first measurement usually changes the statistical information of the second measurement because the first measurement broke the quantum coherence of the system, which is called measurement backaction.

A former theoretical work of Dr. Martí Perarnau Llobet in 2017 pointed out that, without violating the basic requirements of quantum thermodynamics, measurement

Scientists make sound-waves from a quantum vacuum at the Black Hole laboratory — ScienceDaily

[email protected]_84

Researchers have developed a new theory for observing a quantum vacuum that could lead to new insights into the behaviour of black holes.

The Unruh effect combines quantum physics and the theory of relativity. So far it has not been possible to measure or observe it, but now new research from a team led by the University of Nottingham has shed light on how this could be achieved using sound particles. The team’s research has been published today in the journal Physical Review Letters.

The Unruh effect suggests that if you fly through a quantum vacuum with extreme acceleration, the vacuum no longer looks like a vacuum: rather, it looks like a warm bath full of particles. This phenomenon is closely related to the Hawking radiation from black holes.

A research team from the University of Nottingham’s Black Hole Laboratory in collaboration with University of British Columbia and Vienna
