Google Releases AI Quantum Library – Is It to Benefit Google Team X?

  • The purpose of the library is to work with quantum neural networks.
  • A qubit cannot only be in the state "0" or "1" but also in a quantum superposition of these states.
  • The library is not a surprise and the reason behind such a move is to aid Google and their special secret team X.

This week Google released a unique library of programs called TensorFlow Quantum (TFQ). It complements the well-known TensorFlow tool designed to work with artificial intelligence on classic computers. The purpose of the library is to work with quantum neural networks. It can be used both on real quantum computers and on their simulations. It is open source and free.

The project was implemented by the Google AI Quantum team together with students from the University of Waterloo, as well as Alphabet X and Volkswagen.

A qubit cannot only be in the state “0” or “1” but also in a quantum superposition of these states. This potentially provides quantum computers with tremendous computing power. But at the moment, qubit systems are very vulnerable to interference and errors.

TFQ provides tools for working with the main components of quantum computing: qubits, quantum measurement procedure, and so on. The system can be used for programming both real quantum computers and their simulations on classical machines. To solve the latter problem, the Google team also released a qsim quantum computing circuit simulator.

The systems of the NISQ era are vulnerable to interference and computational errors. Google engineers offer their solution: filter out random noise from the data and extract useful information.

According to google,  the world is entering the era of noisy medium-scale quantum processors (Noisy Intermediate-Scale Quantum, or NISQ). Such devices will have 50-100 qubits. At present,  qubits still work erratically. Hence, the application of the term noisy. . At the same time, the error correction algorithms proposed to date will be effective with a computing power of millions. For greater efficiency, they should work in the same system as classic processors.

TFQ is also integrated with the Cirq platform. Cirq: An Open Source Framework for NISQ Algorithms was incepted in 2018.

The library is not a surprise and the reason behind such move is to aid Google and their special secret team X. The purpose of the X is to work on cutting edge technologies. It is important to understand the team does not create their own quantum computers.

The interest is in creating new algorithms and applications to run on quantum computers, and creating software libraries that allow ordinary programmers to use extraordinary machines. The leader of group X has never given an interview and his team is not allowed to ever speak to the media.

Russia seems to believe that team X is working on robomobiles and stratospheric Internet distribution balloons, which have now been separated into separate independent divisions of Alphabet.

According to the bio of the Guifre Vidal he is indeed a Google Team X employee.

Quantum computers and technologies will forge ahead. The key global players continue to put the quantum race at the top of their priorities.
