Quantum computing refers to computing using quantum-mechanical phenomena, such as superposition and entanglement. Quantum computers are different from traditional computers, used majorly to solve problems that the modern classical machines fail to handle.
Quantum computing has been a topic of major research for various companies over the past few years. About two months ago in October, Intel launched its 17- qubit quantum computer. At the time of its launch, Intel stated that qubits are tremendously fragile: any noise or unintended observation of them can cause data loss. This fragility requires them to operate at about 20 millikelvin – 250 times colder than deep space. The 17 qubit machine is built on different architecture that ensures enhanced reliability and thermal performance. It uses scalable interconnect that allows for 10-100x more signals into and out of the chip. Recently, Intel’s CEO, Brian Krzanich, has announced the launch of new 49-qubit quantum computer. This new computer is a grand step towards quantum supremacy. Presumably, all the features of the 17 qubit machine are still baked into this system. It is codenamed as Tangle Lake, which is a reference to an Alaskan lake chain. The increase in the number of qubits makes possible for the computer to solve complex problems and do significant amount of additional work. Intel thinks that a lot more work needs to be done in order to fill the gap between the current position and the position that the company wants to achieve to make possible the commercialization of quantum computing.
