Twist: MIT’s New Programming Language for Quantum Computing

Posted by in categories: computing, quantum physics

Time crystals. Microwaves. Diamonds. What do these three disparate things have in common?

Quantum computing. Unlike traditional computers that use bits, quantum computers use qubits to encode information as zeros or ones, or both at the same time. Coupled with a cocktail of forces from quantum physics, these refrigerator-sized machines can process a whole lot of information — but they’re far from flawless. Just like our regular computers, we need to have the right programming languages to properly compute on quantum computers.

Programming quantum computers requires awareness of something called “entanglement,” a computational multiplier for qubits of sorts, which translates to a lot of power. When two qubits are entangled, actions on one qubit can change the value of the other, even when they are physically separated, giving rise to Einstein’s characterization of “spooky action at a distance.” But that potency is equal parts a source of weakness. When programming, discarding one qubit without being mindful of its entanglement with another qubit can destroy the data stored in the other, jeopardizing the correctness of the program.

Texas Governor Abbott Turns to Bitcoin Miners to Bolster the Grid and His Re-Election

Posted by in categories: bitcoin, business, computing, cryptocurrencies

Last fall, Texas Governor Greg Abbott gathered dozens of cryptocurrency deal makers in Austin where they discussed an idea that, on its face, seemed almost upside down: Electricity-hungry Bitcoin miners could shore up the state’s power grid, a top priority after a deep freeze last winter triggered blackouts that left hundreds dead.

The industry’s advocates have been making that pitch to the governor for years. The idea is that the miners’ computer arrays would demand so much electricity that someone would come along to build more power plants, something Texas badly needs. If the grid starts to go wobbly, as it did when winter storm Uri froze up power plants in February 2021, miners could quickly shut down to conserve energy for homes and businesses. At least two Bitcoin miners have already volunteered to do just that.

First Molecular Electronics Chip Developed — Realizes 50-Year-Old Goal

Posted by in categories: biotech/medical, computing, genetics

A platform for single-molecule measurement of binding kinetics & enzyme activity.

The first molecular electronics chip has been developed, realizing a 50-year-old goal of integrating single molecules into circuits to achieve the ultimate scaling limits of Moore’s Law. Developed by Roswell Biotechnologies and a multi-disciplinary team of leading academic scientists, the chip uses single molecules as universal sensor elements in a circuit to create a programmable biosensor with real-time, single-molecule sensitivity and unlimited scalability in sensor pixel density. This innovation, appearing this week in a peer-reviewed article in the Proceedings of the National Academy of Sciences (PNAS), will power advances in diverse fields that are fundamentally based on observing molecular interactions, including drug discovery, diagnostics, DNA

Benchmarks Confirm Intel’s Latest Core i9 Chip Outperforms Apple’s M1 Max With Several Caveats

Posted by in category: computing

Benchmark results have started to surface for MSI’s new GE76 Raider, one of the first laptops to be powered by Intel’s new 12th-generation Core i9 processor.

Intel previously said that its new high-end Core i9 processor is faster than Apple’s M1 Max chip in the 16-inch MacBook Pro and, as noted by Macworld, early Geekbench 5 results do appear to confirm this claim, but there are several caveats as usual.

Scientists simulate ‘fingerprint’ of noise on quantum computer

Posted by in categories: computing, quantum physics

For humans, background noise is generally just a minor irritant. But for quantum computers, which are very sensitive, it can be a death knell for computations. And because “noise” for a quantum computer increases as the computer is tasked with more complex calculations, it can quickly become a major obstacle.

But because quantum computers could be so incredibly useful, researchers have been experimenting with ways to get around the noise problem. Typically, they try to measure the noise in order to correct for it, with mixed success.

A group of scientists from the University of Chicago and Purdue University collaborated on a new technique: Instead of directly trying to measure the noise, they instead construct a unique “fingerprint” of the noise on a quantum as it is seen by a program run on the computer.

Vibrating atoms make robust qubits, physicists find

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

The team was able to maintain this state of superposition among hundreds of vibrating pairs of fermions. In so doing, they achieved a new “quantum register,” or system of qubits, that appears to be robust over relatively long periods of time. The discovery, published today in the journal Nature, demonstrates that such wobbly qubits could be a promising foundation for future quantum computers.

New qubits stay in “superposition” for up to 10 seconds, and could make a promising foundation for quantum computers.
