The American silicon giant Intel, which was recently outperformed by Samsung in
the chip sales numbers, has achieved a new milestone. Intel’s
Netherlands-based partner QuTech has managed to stuff a
programmable 2-qubit quantum computer on a silicon chip and run
two quantum algorithms.
To make the silicon-based quantum chip a reality,
researchers used a unique variant of the qubit (the primary
computing unit used in quantum computers), known as the spin
qubit. It is an electron excited using microwaves.
Using the spin qubit eliminates the need for the necessary
extreme conditions. For instance, the near-zero temperature and
also the use of superconductors, like in the 17-qubit and the breakthrough
49-qubit quantum computing chips Intel created with
their partner QuTech.
The experiment is more of an effort towards making quantum
computing compatible with the existing technology, rather than
showing off its performance. The presence of silicon is
somewhat assuring; the current computer industry has already
widely explored the material. The researchers say that the
silicon material “naturally causes little disruption to
our qubits” and “silicon quantum chips are very similar to
industrial classic computer chips.”
Despite the ongoing developments in Quantum computing with
scientists being able to control a few qubits reliably, we are
still away from realizing the dream of a real quantum computer.
But with the said development on the table, we might see more
powerful quantum chips capable of executing more complex
algorithms sooner than expected. But to do so, the number
of qubits would have to be increased, according to the
