A chip for quantum computers is presented, operating at a temperature lower than in outer space

Published

New York-based quantum computing startup SEEQC has announced it has created a digital chip that can operate at temperatures lower than outer space, so it can be used with quantum processors, which are often found in cryogenic chambers.

Quantum computers based on quantum physics could one day perform calculations millions of times faster than today’s most powerful supercomputer. One problem is that quantum processors with quantum bits or qubits often need to be stored at very low temperatures, close to zero Kelvin, or -273.15 Celsius. On the other hand, classical computers operate at ordinary temperatures.

Today, wires connect a quantum processor in a freezer to classic computers at room temperature, but temperature changes can slow down the speed and cause other problems. In the same way, SEEQC built its quantum computer and is now trying to modify it with its new chips.

“If you’re trying to build a data center, if that’s your goal, then it’s not enough to take those early prototype designs and try to brute force them to scale,” said John Levy, co-founder and CEO of SEEQC.

The first chip, unveiled this week, sits directly below the quantum processor and controls the qubits and reads the results. At least two other chips, which are still under development, will be in the slightly warmer part of the cryogenic chamber. They can further process the information needed for quantum computing.

This technology could make it easier to build more powerful quantum computers, Levy said, as each cryogenic chamber could support more qubits. Modern superconducting quantum computers have hundreds of qubits, but by some estimates it could take thousands or even a million qubits to build a quantum computer to run useful algorithms.

SEEQC’s digital chips are manufactured at SEEQC’s Elmsford plant using silicon wafers, but no transistors, according to Levy.

Absolutely all Mac computers based on Apple Silicon have a serious GoFetch vulnerability that cannot be fixed at the silicon level

Absolutely all Mac computers based on Apple Silicon have a

Vulnerabilities are found not only in AMD or Intel processors. A fresh vulnerability called GoFetch was found in Apple M single-chip systems for its Mac computers.

Absolutely all Mac computers based on Apple Silicon have a serious GoFetch vulnerability that cannot be fixed at the silicon level

The vulnerability allows attackers to steal cryptographic information from the CPU cache by allowing the attacker to create a cryptographic key from the stolen data, allowing the application to access sensitive encrypted data.

This vulnerability is very dangerous because it completely neutralizes the side-channel encryption algorithm used to protect against side-channel or processor cache attacks.

In addition, there is no way to fix the vulnerability at the silicon level, meaning Apple cannot start producing chips without the vulnerability. But, as in other cases, it is possible to create a software patch, but it is not yet known what share of productivity will have to be paid for this.

In China they imported Apple Mac Studio The SZBOX FN60G

As reported by ITHome, the SZBOX FN60G mini-computer has been introduced in China, which with its aluminum body is very reminiscent of the Apple Mac Studio.

In China, they “imported” Apple Mac Studio.  The SZBOX FN60G mini PC with a volume of only 2.5 liters can install an Intel processor for the LGA1700 socket and GeForce RTX 4060

With a small volume of only 2.5 liters, inside you can install not only any Intel processor for the LGA1700 socket (the only limitation is TDP no more than 100 W), but also a discrete video card. The source talks about a “modified” GeForce RTX 4060 or AMD Radeon RX6600. We are probably talking about models for Mini-ITX cases.

On the inside of the motherboard (the chipset model is not reported) there are two slots for DIMM DDR5 RAM modules (maximum RAM – 64 GB), as well as two M.2 connectors for installing solid-state drives. The interface connectors are well demonstrated in the image below.

SZBOX FN60G is already on sale on Aliexpress, but the price is considerable – 745 euros.

Startup Efficient Computer has unveiled the Monza processor, which the company claims is nearly 100 times more energy efficient than general purpose processors on the market today.

The secret to this potentially revolutionary achievement lies in its reconfigurable architecture and software stack.

Current general purpose processors are too general purpose and waste the vast majority of their energy (>99%) on unimportant internal data movement and instruction management overhead. Scaling performance requires complex power-intensive optimizations that further increase power consumption. The inefficiency of these designs causes the battery to drain quickly, limiting the device's capabilities and requiring frequent recharging or battery replacement.

Efficient's new Fabric architecture is a unique approach to general-purpose computing that eliminates the excessive power overhead inherent in existing general-purpose computing architectures. The new Efficient architecture significantly improves the energy efficiency of chips, bringing computing capabilities to use cases that were previously not possible due to limited energy availability. For example, a smartwatch or wearable health device can last for weeks on a charge and support more sophisticated analysis of sensor data, while a remote sensing satellite can provide highly accurate data using the limited energy of a nanosatellite's small battery

The company notes that compared to modern GPUs, its chip consumes three orders of magnitude less energy. The Fabric architecture was developed through more than seven years of research at Carnegie Mellon University, and the company's website includes links to scientific papers.

The company provides very few technical details, and nothing is reported at all about the Monza test processor. Given the claims of a revolutionary breakthrough in energy efficiency, this is somewhat strange.
