Google’s quantum processor ‘Bristlecone’ to outperform conventional computers

Traditional system chip designs are operating out of the stream with low performance and Quantum computers are emerging as a ray of hope for next generation.

Google's latest quantum processor 'Bristlecone' is believed to outclass the classical computers operating in the silicon processors. According to Google, the Bristlecone computing chip has 72 qubits to reach quantum supremacy in the near-future.

Quantum computers differ from traditional computers in the way that they use quantum bits, or qubits, to encode information rather than using bits represented by 0's and 1's in the classical systems. A qubit is a quantum system that encodes the zero and the one into two apparent quantum states. They operate at very low temperatures and are protected from the environment to avoid errors from noise.

Even though Quantum computing is a long-term goal but many companies have already started testing quantum-computers. Traditional system chip designs are operating out of the stream with low performance and Quantum computers are emerging as a ray of hope for next generation.

Google stated, "The intention of this gate-based superconducting system is to offer a testbed for research into system error rates and scalability of our qubit technology, as well as applications in quantum simulation, optimization, and machine learning."

Before quantum computers could replace conventional systems, the developers need to assure that they have low error rates. Google had formerly demonstrated the quantum system with an error rate of 1% for read-out, 0.1 percent for single-qubit and 0.6 percent for two-qubit gates.

Quantum computing might be good for artificial intelligence tasks like self-driving cars, optimizing warehouse operations or setting e-commerce product prices. Other real-life applications may include Radiotherapy optimization, protein folding, water network optimization, machine-learning, object-detection, video compressions and much more.

Many other tech-giants are in the race to test quantum computers. IBM presently has a 50-qubit machine in its lab and its developers are working with the cloud-based simulation of quantum computers. Moreover, Microsoft is also working on the same platform and will soon come up with its new approach.
