IBM unveiled its first modular quantum computer powered by 133 qubit Heron quantum processor

Quantum computing engineers at IBM focusing now one improving the reliability of qubits along with increasing the number of qubits. Qubits which are basic quantum states are prone to errors in maintaining the defined state. It is more important to develop a quantum processor with reliable low error qubits rather the number of qubits. In this direction IBM has announced a new quantum chip called Heron with 133 qubits with very lowest error rate. Heron is a utility-scale quantum processor. In Heron, IBM used a technique called quantum low-density parity check (qLDPC) to take care of error correction. IBM also did some architectural changes featuring better modularity and scale.
IBM Quantum Heron is a 3-5x improvement in device performance over our previous flagship 127-qubit Eagle processors, and virtually eliminates cross-talk. IBM also announced its first model lot quantum computer called IBM Quantum System Two. IBM Quantum System Two, located in Yorktown Heights, New York, has begun operations with three IBM Heron processors and supporting control electronics. IBM said Heron is the first in IBM's new class of performant processors with significantly improved error rates, offering a five-times improvement over the previous best records set by IBM Eagle. IBM also announced its Quantu...
