The latest advance in the field has come from IBM

The latest advance in the field has come from IBM, which unveiled the Eagle processor this week. Boasting 127 qubits (quantum bits) of quantum power, it doubles the power of China’s Zuchongzhi processor, previously the world’s most advanced.

The new quantum processor breaks the previous barrier of 100 qubits, the most basic units of information in a quantum computer. To give an idea of scale, the number of bits (a one or a zero in a normal computer) needed to match the computing power of the 127-qubit processor would exceed the total number of atoms in the more than 7.5 billion people alive today, according to IBM.

The breakthrough is significant, but we are still a long way from quantum computers taking computing to new heights in our daily lives. For that to happen, their power will need to be around one million qubits.

said Spain’s Darío Gil, IBM’s vice president and director field has come from IBM of research, in a statement. The technology company aims to have a new 433-qubit processor ready next year, and a 1,121-qubit processor by 2023.

IBM and Google are vying to produce the first quantum computer for commercial use, though companies such as Microsoft and Intel are also in the race. On a geopolitical level, the main players are the US and China, with Europe as an observer. When it comes to R&D investment, China’s spending is unrivaled: between 2017 and 2020 it invested $10 billion (€8.9 billion) in quantum computing programs at its research centers.

The US has set aside $1.2 billion (€1.06 billion) until 2023, while the EU will assign $1 billion (€890 million) until 2026.

Theoretical physics turned reality
As its name suggests, quantum computing borrows from quantum physics – the study of matter at subatomic levels – to offer the possibility of vastly increased computing power. Conventional computers work with the binary system of the digits 0 and 1. In a state-of-the-art microchip, there are billions of transistors, capable of performing complex operations in seconds.n these physical barriers because quantum bits, or qubits, can be both 0 or 1 at the same time, a concept known as superposition, or existing in multiple states at once. with 10, 1,024, and so on.

The development of the infrastructure needed to host and exploit qubits is extremely complex. Engineers have had to deal with problems such as cooling the processor (qubits need to operate at temperatures close to absolute zero, or -273 degrees Celsius) and in total isolation, as any vibration (such as noise) can destabilize them.

One downside: the encryption in use for digital security today will become vulnerable when quantum computing reaches a certain state of maturity. IBM has recognized the “responsibility” it has to mitigate the risks it is introducing into the digital world. Companies and individuals will have to opt for new data security measures in the future that quantum computing cannot breach.
