Rigetti has taken the next step with their 80 qubit Aspen-M-1 processor by making it commercial available on both Rigetti's Quantum Cloud Service (QCS) and also on the Amazon Braket service. Previously, this machine was only available for private beta testing through QCS.

In association with this announcement, Rigetti also announced several performance metrics with this machine. They have adopted the use of the CLOPS (Circuit Layer Operations per Second) metric originally proposed by IBM. They reported that using the standard 100 shot measurement procedure described by IBM, they achieved a measure of 844 for the 40-qubidt machine and 892 for the 80-qubit machine. This is not too different from IBM's current measurements of 850 for their 127 qubit processor, 1500 for their 65 qubit processor and 2400 for their 27 qubit processor. (IBM has made some improvements in these measures since their original paper was published in October 2021.) Rigetti notes that their CLOPS measurement did not decrease as the machine gets larger. They also mentioned that this performance improves significantly to over 7500 as the number of shots increases to 1000. Rigetti has long been a proponent of tightly coupling the classical and quantum processor together for hybrid quantum computing and it is not surprising their systems perform well in this measure.

In addition, Rigetti has also made continued improvements in the coherence and fidelity measurements as shown in the table below (as of February 2022).

In another announcement, Rigetti announced that they have reached a collaborative agreement with Nasdaq (Nasdaq:NDAQ) to explore quantum applications to help solve high-impact computational problems in the financial industry. This research will utilize Rigetti's Quantum Cloud Services and the 80 qubit processor.

Rigetti has released several announcements, blogs and web pages with additional information. You can find the press release announcing the availability of the 80 qubit Aspen-M here, another press release announcing their teaming with NASDAQ here, a blog post describing their optimization of full-stack throughput and fidelity here, and performance information on their Aspen-11 and Aspen-M-1 processors here. In addition, Amazon has posted a blog announcing their support for Rigetti's 80 qubit processor here and has an additional web page describing the Rigetti processors here.
