2025 will see huge advances in quantum computing. So what is a quantum chip and how does it work?

Motion Loop/Shutterstock Muhammad Usman, CSIROIn recent years, the field of quantum computing has been experiencing fast growth, with technological advances and large-scale investments regularly making the news. The United Nations has designated 2025 as the International Year of Quantum Science and Technology. The stakes are high – having quantum computers would mean access to tremendous data processing power compared to what we have today. They won’t replace your normal computer, but having this kind of awesome computing power will provide advances in medicine, chemistry, materials science and other fields. So it’s no surprise that quantum computing is rapidly becoming a global race, and private industry and governments around the world are rushing to build the world’s first full-scale quantum computer. To achieve this, first we need to have stable and scalable quantum processors, or chips. What is a quantum chip? Everyday computers – like your laptop – are classical computers. They store and process information in the form of binary numbers or bits. A single bit can represent either 0 or 1. By contrast, the basic unit of a quantum chip is a qubit. A quantum chip is made up of many qubits. These are typically subatomic particles such as electrons or photons, controlled and manipulated by specially designed electric and...

DRDO’s young scientists complete testing of 6-qubit quantum processor

New Delhi, (IANS): Scientists from DRDO's Young Scientists Laboratory for Quantum Technologies (DYSL-QT) have completed end-to-end testing of a 6-qubit quantum processor, the Ministry of Defence said.“The project executed at TIFR Mumbai’s Colaba campus is a three-way collaboration between DYSL-QT, TIFR and Tata Consultancy Services (TCS). The DYSL-QT scientists put together the control and measurement apparatus using a combination of commercial off-the-shelf electronics and custom-programmed development boards,” the ministry said.It added that these qubits were designed and fabricated at TIFR and the quantum processor architecture is based on a novel ring-resonator design invented at TIFR. The cloud-based interface to the quantum hardware is developed by TCS.“The scientists are now working on optimising various aspects of the system performance before it becomes ready for operation,” the ministry said.The ministry added that plans are underway to provide wider access to this system for education, and research and eventually as a test bed for testing superconducting quantum devices for analysis.“The next development target is to scale up the number of qubits and assess the scaling trends to technology challenges, development effort/time and monetary resources required for development, operations and commercialisation of various sizes...
