The rapidly evolving and occasionally divisive area of quantum computing, which draws on the peculiarities of quantum physics, is still in its early stages. The potential for quantum computers to transform fields like drug discovery and climate science is enormous. They have much faster computation speeds than their traditional counterparts.
However, there are some potential drawbacks to this advanced technology. Quantum computers are high on the list of threats to national security because they present significant difficulties for current encryption systems.
The contentious conversation goes on. These quantum machines still need to demonstrate more practicality outside of academic research, according to critics, despite the impressive milestones.
The Sycamore quantum processor, Google's most recent quantum machine, currently has 70 qubits. Compared to its predecessor, which had 53 qubits, this is a significant improvement. As a result, the new processor is roughly 241 million times more durable than the previous model.
The ability to store and process this level of quantum information is an achievement that neither the fastest nor the slowest classical computer can match because each qubit can exist in a state of zero, one, or both simultaneously.
In a paper that was published on the arXiv pre-print server, the Google team stated: Quantum computers have the potential to carry out tasks that are beyond the capabilities of conventional computers. We demonstrate that our experiment is beyond the capabilities of existing classical supercomputers by estimating the computational cost in comparison to improved classical methods.
Even the fastest classical computers now in operation, such as the Frontier supercomputer in Tennessee, might get surpassed by quantum computers in the future. Conventional machines are restricted to a dual-state reality of ones and zeros and run on the language of binary code. The quantum paradigm, on the other hand, defies this restriction.
The manufacturing cost of Google's quantum computer is still unknown. In any case, this development undoubtedly holds the promise of revolutionary computational power.
For instance, the Frontier supercomputer would be able to match a calculation made by Google's 53-qubit computer in just 6.18 seconds, as stated by the Google team. However, Google's most recent 70-qubit device would require the same machine for 47.2 years to perform the same computation.
Google's significant progress has been praised by numerous experts in the field. Google's progress was described as a "major milestone" by Riverlane CEO Steve Brierley. Riverland is based in Cambridge.
He also said, " The argument regarding whether or not we could achieve quantum supremacy has been settled.
In a similar vein, the director of the Sussex Centre for Quantum Technologies, Professor Winfried Hensinger, commended Google for resolving a particular academic issue that was difficult to compute on a conventional computer.
In the words of Professor Hensinger, "Their most recent demonstration is yet another powerful demonstration that quantum computers are developing at a steady pace."
He emphasized that the development of quantum computers with the ability to correct their inherent operational errors would be the next crucial step.
Although IBM has not yet commented on Google's recent work, it is evident that researchers and businesses around the world are interested in this quantum-computing advancement. The development of computational technology, will open up new opportunities and create competition. The games should begin!
