A piece of the quantum puzzle (Image 5)

A superconducting qubit chip with a few qubits on it


A superconducting qubit chip with a few qubits on it. The size of the chip is about 6 mm by 6 mm. The wafer was made by depositing 200 nanometers of aluminum on a sapphire substrate, followed by a multi-layer lithography process, to nano-fabricate various elements of the quantum processor.

More about this image
Starting early this century, scientists have been working hard to exploit the strangeness of quantum mechanics and make a quantum computer. The superior computational processing power of quantum bits (qubits) is poised to have revolutionary impacts on diverse fields ranging from chemistry to economics. In the race to find a reliable platform for making quantum computers, superconducting qubits are among the leading ones.

In 2014, scientists at the University of California, Santa Barbara, in collaboration with Boston University, used one of these chips to study quantum topology and showed how superconducting qubits can help to make topological concepts tangible. Topology, in spite of its abstract mathematical constructs, often manifests itself in physics and has a pivotal role in understanding of natural phenomena. Notably, the discovery of topological phases in condensed-matter systems has changed the modern conception of phases of matter. In their research, the scientists found a novel method to directly measure topological properties of quantum systems.
