IonQ introduces multi-core chip for quantum computing

The U.S. company IonQ wants to provide additional performance for quantum computers with its new multi-core chips. The combination of four chains of 16 ions each provides enormous extra performance when daisy-chained.

IonQ relies on its quantum computing hardware to excite ions held in electrical traps. The newly unveiled multi-core chip traps four chains of 16 ions each, which can be driven together and apart by electric fields.

They can communicate with each other at the quantum level, enabling significant performance gains. IonQ calls this solution a “reconfigurable multicore quantum architecture.” In this process, electric fields rotate, thus holding the electrically charged atoms (ions) in a high vacuum.

To control the heat generation, the ions are irradiated with lasers until they come to rest almost completely and are lined up in space almost like a chain. Higher excitation of the ions is also triggered by a laser. This is how the qubits that quantum computers use to compute are created.

The interaction of multiple qubits is also triggered by a laser that causes the ions to oscillate collectively. IonQ uses traps made of fused silica, into which metallic structures have been incorporated. Specially developed photonic compounds enable the qubits on one chip to be connected to those on another.

How powerful this new system is remains to be seen in the long term. In April, Honeywell presented a silicon chip on which individual qubits can be linked to one another via so-called quantum gates.
