IBM Plans Quantum Processor with 4158 Qubits
IBM has renewed its roadmap for the development of quantum computers. By 2025, the manufacturer wants to develop a quantum processor with 4158 qubits.
IBM has presented an updated roadmap for developments in the field of quantum computing. After the manufacturer presented a 127-qubit quantum processor called Eagle at the end of 2021, the company continues to raise expectations: IBM wants to develop a processor with 1121 qubits by 2023, according to a statement.
However, this processor, called Condor, is likely to be the last of its kind. Because in order to further scale up the computing power and to facilitate the manufacturing process, IBM will be relying on “scalable quantum hardware” in the future. The manufacturer speaks accordingly of the introduction of “modular” quantum computing. The manufacturer plans to develop a modular quantum processor with 4158 qubits by 2025.
IBM wants to test different approaches to increase the performance of the processors. The first is to improve communication and the parallelization of processes across multiple processors. Second, IBM wants to connect multiple chips to larger processors using couplers. And thirdly, the manufacturer is planning so-called Quantum Communication Links, with which several processors can be coupled with one another without conversion to bits, which should ultimately make complex distributed calculations possible.
By the way: two Australian physicists have taught IBM quantum computers to simulate the largest time crystal to date. They thus eclipsed a record that more than 100 researchers had set last summer with a quantum computer from Google.
