Quantum Computing and Computational Biology: Peptide Binding Classification on Quantum Computers

29 November 2023 at 11:07
Researchers from Quantinuum and Amgen have conducted a study on using quantum computers for computational biology. They built quantum models to perform sequence classification relevant to the design of therapeutic proteins. The models were run on emulators of state-of-the-art noisy quantum processors and then on the Quantinuum H1-1 trapped-ion quantum processor. The results were in close agreement with noiseless exact simulation. This work is the first application of near-term quantum computing to a task critical to the design of therapeutic proteins, suggesting potential for larger-scale applications in this and related fields. The work is published in Arxiv, "Peptide Binding Classification on Quantum Computers".

Atom Computing Achieves High-Fidelity Quantum Error Correction in 171Yb Atomic Array.

By: The Quant
27 November 2023 at 14:54
Atom Computing, a Boulder-based company, has developed a scalable, high-fidelity method for midcircuit measurement in quantum computing. The team used a single-species tweezer array of neutral 171Yb atoms to perform nondestructive state-selective and site-selective detection. This allows a subset of qubits to be measured while causing only percent-level errors on the remaining qubits. The technique also demonstrated the ability to reuse ancilla qubits and perform conditional refilling of ancilla sites to correct for occasional atom loss, while maintaining the coherence of data qubits. The research was led by M. A. Norcia and B. J. Bloom.

Exascale Supercomputers Revolutionise Material Simulations, Paving Way for Fuel-Efficient Cars and Novel Superconductors

25 November 2023 at 10:06
Researchers at the University of Michigan have used the world's most powerful supercomputer, Frontier, to simulate the behaviour of up to 600,000 electrons within a microscopic chunk of a magnesium alloy. This breakthrough could lead to the design of lightweight alloys for fuel-efficient cars and airplanes. Frontier, located at the Department of Energy’s Oak Ridge National Laboratory, is capable of 1.1 billion billion operations per second. It is expected to be surpassed by Aurora, another US supercomputer, which will aid in designing more fuel-efficient airplanes and predicting patient responses to cancer treatments.

Chinese Scientists Enhance Security of Zero-Knowledge Proofs with Quantum Technology

24 November 2023 at 07:57
A team led by Prof. Jianwei and Prof. Qiang from the University of Science and Technology of China (USTC) has improved the security of non-interactive zero-knowledge proof (NIZKP), a cryptographic tool used in digital signatures, blockchain, and identity authentication. The team used a quantum random number generator to create a public service system that broadcasts secure random numbers in real time. They also developed a quantum secure signature algorithm to ensure the integrity of these numbers during transmission. This research combines quantum nonlocality, quantum secure algorithm, and zero-knowledge proof, enhancing the security of NIZKP.

What are Qubits? A brief look into the fundamental technology driving Quantum Computers

By: The Quant
20 November 2023 at 11:36
Qubits, or quantum bits, are the fundamental units of quantum information. Unlike classical bits, which can be either 0 or 1, qubits can exist in a superposition of both states simultaneously. This property, along with quantum entanglement (where qubits become interconnected and the state of one instantly affects the state of another, regardless of distance). The principles of quantum mechanics govern the behavior of qubits, and harnessing their unique properties gives quantum computers their potential power.
