IBM claims to have taken a big step toward a practical quantum calculation. The company introduced the Eagle, a 127-qubit quantum processor. IBM claims that this is the first such processor that cannot simulate a classic supercomputer.
IBM’s quantum Eagle processor has 127 qubits
IBM attributes to progress to a new design that places processor control components on multiple physical levels, while qubits are on a single layer. It is a design that the company says allows for a significant increase in computing power. One aspect of Eagle that the company is not currently talking about is quantum volume. It is a metric that tries to measure the performance of a quantum computer by taking a holistic view of its various parts. Not only does it take into account the cubes, but also the way they communicate with each other. The larger the quantum volume, the more capable the quantum computer is to solve difficult problems.
Without knowing the quantum volume of the Eagle processor, it is difficult to say how it compares to what already exists. Last October, Honeywell claimed that its System Model H1 has a quantum volume of 128 with only 10 connected qubits. What is also noticeable about Eagle is that IBM does not claim quantum supremacy. According to the company, it is a step towards a turning point, but the processor is not yet at the point where it can solve problems that classic computers cannot.
