Olalot: Amazon presents his first quantum computing chip

Amazon introduced Olalot, its first quantum computing chip. The news brings the giant closer to its great cloud rivals, Microsoft and Google, who have also revealed their own quantum chips in recent months, respectively Majorana and Willow.

She has long invested in the quantum computing space, starting in 2019 with her quantum computing service, Braket. At the time, it was launched in partnership with industry players as Quera and Rigetti.

Quantum computing is based on principles of quantum mechanics, taking advantage of “quantum bits” to perform complex calculations faster than traditional computers. Potential applications include drug discovery, encryption, safety and artificial intelligence (AI).

Part of the enthusiasm of companies with technology derives from understanding that there are limits that need to be overcome hardware so that better software can be developed. And, in the case of hardware, It is not enough just to improve what exists, but you need to find new more powerful technologies.

Advances

Building quantum chips that work with less errors is understood as crucial for the advancement of quantum computing as a whole. And it has been a greater challenge than many imagined and one of the limiting factors for quantum computing today.

One of the biggest challenges with quantum computers is their high sensitivity to the lowest changes in the environment. Vibrations, heat, electromagnetic interference of cell phones and wi-fi networks, or even cosmic rays and radiation of outer space, can take quibits out of their quantum state, causing errors.

The alternative used by quantum computer developers is the correction with special codifications of quantum information in various quibitssays the form of logical logical qubits.

There are already options to get accurate results. However, currently, Given the large number of quibits needed to get accurate results, the cost for correction of quantum errors is very high And therefore, it makes it unfeasible to large -scale production of such computers.

Gains

The gains that are expected with quantum computing are many. Last year, Chinese scientists announced the breaking of RSA encryption with quantum computing and some crypto enthusiasts expressed concern about the possible break in bitcoin’s encryption.

In the case of Ocelot, the chip was developed in partnership with the California Institute of Technology (Caltech) and integrates two stacked silicon microchips on each other. Amazon says chip design could reduce costs associated with error correction by up to 90%.
