Quantum computers have the potential to outperform even the most powerful supercomputers by leveraging the laws of quantum mechanics for their computation. The qubits (quantum bits) that perform those operations are in quantum states that are susceptible to environmental effects‚ which can lead to errors. For this reason‚ error correction is a big focus in the field. A company has now presented a bold new approach to how this can be done.A quite common approach to error correction is to surround your computing qubit with a large number of qubits that can make sure it is functioning correctly. This number can vary between 1‚000 and 10‚000 qubits working to correct a single one. This is seen as a "brute force" approach to the problem‚ but it is clear that it requires a lot of qubits for not much computation.Several models have tried to solve this‚ bringing the number of qubits down to at least a comparable number. Academic research has been looking at ways to work on correction directly on one qubit‚ with some breakthroughs in how long a qubit works before succumbing to the “noise” – temperature changes‚ magnetic fields‚ and a wide variety of other factors.A single-qubit approach to correction has also now been announced by startup Nord Quantique. The Canadian company has announced that they can do it without extra qubits‚ the first in the industry to do so. Their method reduces errors by 14 percent on a single qubit by itself.Their quantum system uses a cavity of ultrapure and superconducting aluminum. Microwave photons are introduced in the cavity and they are placed in specific quantum states to do the computation. The team believes that they can build a quantum computer with 100 logical qubits and a handful of physical ones that help reduce the other types of errors. Using photons as bosonic qubits they will be able to reach faster speeds‚ up to 1‚000 times faster than other quantum computing architectures.                 “Our model incorporates redundancy into every logical qubit‚ drastically reducing the number of physical qubits required for error correction once scaled. This positions us well to develop highly efficient and scalable quantum computers‚ without the need for vast amounts of physical qubits devoted to error correction‚ and potentially reaching fault-tolerance in a shorter time‚” Julien Camirand Lemyre‚ President and CTO at Nord Quantique‚ said in a statement.The road to fully scalable error-free quantum computers is far from straightforward‚ so the exploration of different methods is key to finding winning architectures that could move the technology forward.

China’s answer to the Hyperloop‚ an ultra-high-speed maglev train‚ has recently broken its own speed record by achieving speeds over 623 kilometers (387 miles) per hour at a full-scale test track.The project is being run by the China Aerospace Science and Industry Corporation (CASIC)‚ a state-owned aerospace company that makes everything from rockets and missiles to satellites and spacecraft.In 2023‚ the train reached a record-breaking speed of 623 kilometers (387 miles) per hour in a test run under non-vacuum conditions. As reported by the South China Morning Post‚ CASIC claims that new tests have surpassed the previous record. The exact speed is reportedly remaining classified for now.What's more‚ the test was performed in a low-vacuum tube‚ proving the maglev technology works as intended. The advanced train system smashed the speed record at a full-scale 2-kilometer (1.2-mile) test line in the city of Datong in Shanxi province‚ northern China.The vehicle relies on maglev technology‚ which uses magnetism to propel the train forward‚ as well as levitate it above the tracks thereby reducing friction. To further boost its speed‚ the train travels through a specially designed low-vacuum tube that reduces air resistance.The technology is advancing at a mindblowing speed. In October 2022‚ CASIC boasted a train test run that reached speeds of 130 kilometers (81 miles) per hour. The latest attempt is well over four times that speed.                        More could still be yet to come too. CASIC has previously expressed interest in shuttling trains at a maximum speed of 1‚000 kilometers (620 miles) per hour and they’re looking to create technologies that could go as fast as 4‚000 kilometers (2‚485 miles) per hour. Before the CASIC's record‚ the fastest hyperloop speed was 463 kilometers (288 miles) per hour‚ achieved by a team of engineers at the Technical University of Munich in July 2019.As of 2018‚ there were only six maglev train systems in operation across the world: three in China‚ two in South Korea‚ and one in Japan. All of these trains travel in the open air‚ as opposed to ones that use low-pressure tunnels known as hyperloops. While maglev trains can travel at impressively fast speeds‚ they are extremely expensive. They also use vast amounts of energy and require their own dedicated infrastructure that's tricky to integrate into existing transportation systems.Meanwhile‚ outside of China‚ Hyperloop One‚ the company behind a futuristic transportation system once touted by Elon Musk‚ shut down late last year.The dream of hyperloop technology is clearly not dead yet‚ though. There has been talk of a commercial hyperloop system in Italy‚ connecting Venice-Mestre and Padua in less than 15 minutes. Bear in mind‚ however‚ that the train journey time between Mestre and Padova currently takes around 14 minutes.
