Now, scientists have found a way to achieve high-fidelity quantum teleportation using logical qubits. The study was led by researchers from Quantinuum, a quantum computing company based in Colorado, USA.
Interesting Engineering (IE) spoke to one of the co-authors of the study, David Hayes, Director of Computation Theory and Design at Quantinuum.
“Quantum teleportation is an important technique that allows quantum information to be moved quickly, enabling fast processing in quantum computation. It’s also used as a benchmark for general progress since it requires several complex operations to work together,” Hayes explained to IE.
Quantum computing offers mind-boggling problem-solving potential. Here are four ways to buy quantum computing stocks.
Scientists from the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) and MIT
MIT is an acronym for the Massachusetts Institute of Technology. It is a prestigious private research university in Cambridge, Massachusetts that was founded in 1861. It is organized into five Schools: architecture and planning; engineering; humanities, arts, and social sciences; management; and science. MIT’s impact includes many scientific breakthroughs and technological advances. Their stated goal is to make a better world through education, research, and innovation.
India’s semiconductor market is poised for rapid growth, with projections estimating its value to reach $63 billion by 2026.
Seagate started shipping hard drives with HAMR tech in December 2024, turning a long-awaited technological advancement into a commercial reality. Now, the storage specialist is announcing that even more advanced HAMR drives, with capacities of up to 36 terabytes, are on the way.
The 36TB HAMR drives are being shipped to a select group of customers for testing and validation. Like the earlier HAMR units, these new Exos M drives are built on the Mozaic 3+ technology platform to deliver “unprecedented” areal density. The drives utilize a complex 10-platter design, achieving an areal density of 3.6TB per platter.
According to Seagate CEO Dave Mosley, the company has already reached an areal density of over 6TB per disk in its test environments. The goal, he says, is to further increase the data density to 10TB per platter. Seagate also states that Mozaic 3+ is a highly efficient storage platform, enabling the new Exos M drives to lower the total cost of ownership and reduce energy consumption.
Scientists used antimony atoms to improve quantum computing by making qubits more stable, like a quantum cat, and error-resistant.

The core components of CRISPR-based genome-editing therapies are bacterial proteins called nucleases that can stimulate unwanted immune responses in people, increasing the chances of side effects and making these therapies potentially less effective.
Researchers at the Broad Institute of MIT and Harvard and Cyrus Biotechnology have now engineered two CRISPR nucleases, Cas9 and Cas12, to mask them from the immune system. The team identified protein sequences on each nuclease that trigger the immune system and used computational modeling to design new versions that evade immune recognition. The engineered enzymes had similar gene-editing efficiency and reduced immune responses compared to standard nucleases in mice.
Appearing today in Nature Communications, the findings could help pave the way for safer, more efficient gene therapies. The study was led by Feng Zhang, a core institute member at the Broad and an Investigator at the McGovern Institute for Brain Research at MIT.
Computers also make mistakes. These are usually suppressed by technical measures or detected and corrected during the calculation. In quantum computers, this involves some effort, as no copy can be made of an unknown quantum state. This means that the state cannot be saved multiple times during the calculation and an error cannot be detected by comparing these copies.
Inspired by classical computer science, quantum physics has developed a different method in which the quantum information is distributed across several entangled quantum bits and stored redundantly in this way. How this is done is defined in so-called correction codes.
In 2022, a team led by Thomas Monz from the Department of Experimental Physics at the University of Innsbruck and Markus Müller from the Department of Quantum Information at RWTH Aachen and the Peter Grünberg Institute at Forschungszentrum Jülich in Germany implemented a universal set of operations on fault-tolerant quantum bits, demonstrating how an algorithm can be programmed on a quantum computer so that errors can be corrected efficiently.
