No offense, but he said what we all knew deep down tbh. Qc is far off and we all believed in the potential… without a clue when that would be obtainable

Here is your DD about Rigetti

A reminder for everybody:

In 2017, Rigetti built an 8-qubit quantum computer and deployed it to the cloud (see Fig. 1).

https://arxiv.org/pdf/1706.06570

In 2017, Rigetti built a 20-qubit quantum computer and used it to solve a combinatorial problem with machine learning (see Fig. 2).

https://arxiv.org/pdf/1712.05771

In 2021, Rigetti demonstrated, for the first time, the entanglement between two qubits fabricated on two separate chips. This work was published in Nature.

https://arxiv.org/pdf/2102.13293

In 2021, Rigetti invented a new type of tunable coupler which unlocks fast and high-fidelity two-qubit gate operations.

In 2021, Rigetti discovered that quantum circuit Born machines show superior performance compared to restricted Boltzmann machines in modeling financial data.

In 2024, Rigetti discovered a new fabrication technique that improves the relaxation time of superconducting qubits. This work was published in Nature.

In 2024, Rigetti discovered a new technique for adjusting the resistance of Josephson junctions at room temperature. This discovery makes it easier to scale quantum computers based on superconducting qubits. The results were published in Nature.

At the end of 2024, Rigetti built a quantum computer with 84 qubits with a two-qubit gate fidelity above 99%. This quantum computer has a similar performance to Willow, the chip built by Google.

Seems like they are making incremental progress but still far from having truly practical or scalable applications yet. It will be impressive once you can run general purpose models like climate simulations with quantum computers.
