Scientists just made quantum computer operations 1

Researchers have found a way to perform certain quantum operations more than 1,000 times faster, cutting thousands of repeated control cycles down to just one. The advance could reduce errors and bring reliable, fault-tolerant quantum computers closer to reality. Scientists just made quantum computer operations 1,000 times faster.

Scientists just made quantum computer operations 1,000 times faster Science News from research organizations Scientists just made quantum computer operations 1,000 times faster A new quantum computing method can make advanced operations more than 1,000 times faster, potentially removing a major barrier to reliable quantum machines. The longer a quantum operation takes to complete, the more time there is for those errors to build up. Researchers at Chalmers University of Technology in Sweden have now developed a method that can perform a broad range of advanced quantum operations more than a thousand times faster.

The advance tackles a major obstacle in the field and could help move quantum computing closer to becoming fault-tolerant. Quantum computers could eventually transform areas such as drug discovery, energy technology, cryptography, artificial intelligence, and logistics. Before that can happen, however, these machines need to become much more dependable.

Scientists have directly observed how two negatively charged DNA molecules can pair up despite normally repelling each other. Positively charged metal ions appear to bridge the gap, helping matching DNA helices align groove for groove like a molecular zipper.

The discovery confirms a theory proposed two decades ago and could help researchers understand DNA interactions involved in cancer and other cellular processes. Scientists capture two DNA strands zipping together for the first time.

Because objects with the same charge normally push away from each other, DNA molecules might be expected to repel one another. Yet inside living cells, DNA must sometimes come into close contact and recognize matching sequences.

These interactions are essential for processes including genetic recombination and gene silencing, and they can also play a role in cancer. Scientists have now captured a remarkably detailed view of how this happens.

Using powerful atomic force microscopy, researchers watched short pieces of DNA align with extraordinary precision, matching one another groove for groove.

Why Quantum Computers Are So Error-Prone A major challenge is that quantum computations can be disrupted by extremely small environmental effects.
