An interdisciplinary team led by researchers at the University of California, Los Angeles (UCLA) developed a method for building quantum computers based on atomic building blocks that are custom-designed by chemists.
The researchers developed small molecules containing calcium and oxygen atoms that act as qubits and form a functional group that can be inserted into virtually any other molecule, passing on their properties to those molecules.
The researchers observed that these qubits retain their structure when attached to bigger molecules and can withstand laser cooling.
Said UCLA's Eric Hudson, "If we can bond a quantum functional group to a surface or some long molecule, we might be able to control more qubits. It should also be cheaper to scale up, because an atom is one of the cheapest things in the universe. You can make as many as you want."
