Amazon Web Services (AWS) strives to deliver reliable services that customers can trust completely. This requires maintaining the highest standards of security, durability, integrity, and availability—with systems correctness serving as the cornerstone for achieving these priorities. An April 2015 article published in Communications of the ACM, titled “How Amazon Web Services Uses Formal Methods,” highlighted the approach for ensuring the correctness of critical services that have since become a

Choose wisely! The correct answer, the explanation, and an intriguing story await. Correct Answer: Four times louder What was Comdex before it was shut down in the early 2000s? The decibel (dB) scale is logarithmic, not linear, increasing by a power of ten with every 10dB, which roughly equates to a doubling in loudness based on average human hearing. Consequently, 30dB is about twice as loud as 20dB, and a computer producing 40dB of noise would be approximately four times louder than one gen

The baby who was treated, Kyle “KJ” Muldoon Jr., suffers from a rare metabolic condition caused by a particularly unusual gene misspelling. Researchers say their attempt to correct the error demonstrates the high level of precision new types of gene editors offer. “I don’t think I’m exaggerating when I say that this is the future of medicine,” says Kiran Musunuru, an expert in gene editing at the University of Pennsylvania whose team designed the drug. “My hope is that someday no rare disease

In a scene from the movie Gladiator, Roman emperor Marcus Aurelius, worried about the fragility of his empire, tells his general, Maximus: “There was once a dream that was Rome. You could only whisper it. Anything more than a whisper and it would vanish.” The same could be said qubits. They are foundational components of quantum computers, and are one of thornier challenges in getting stable and usable systems up and running. A key reason is how fragile they are and how easily they can lose the

Amazon Web Services has unveiled its Ocelot chip based on a hardware-efficient quantum computing architecture. Fernando Brandão and Oskar Painter of AWS said in a blog post that the pair of silicon microchips that compose the Ocelot logical-qubit memory chip represent the company’s first-generation quantum chip, and it could reduce the costs of implementing quantum error correction by up to 90%. Ocelot represents Amazon Web Services’ pioneering effort to develop, from the ground up, a hardware

Ocelot consists of nine quantum bits, or qubits, on a chip about a centimeter square, which, like some forms of quantum hardware, must be cryogenically cooled to near absolute zero in order to operate. Five of the nine qubits are a type of hardware that the field calls a “cat qubit,” named for Schrödinger’s cat, the famous 20th-century thought experiment in which an unseen cat in a box may be considered both dead and alive. Such a superposition of states is a key concept in quantum computing. T

Following up on Microsoft's announcement of a qubit based on completely new physics, Amazon is publishing a paper describing a very different take on quantum computing hardware. The system mixes two different types of qubit hardware to improve the stability of the quantum information they hold. The idea is that one type of qubit is resistant to errors, while the second can be used for implementing an error-correction code that catches the problems that do happen. While there have been more effe
