Osprey is nearly quadruple the size of Eagle at 433 qubits. The larger chip sizes have required further enhancements to device packaging, as well as custom flex cabling in the cryostat to fit the greater I/O requirements within the same wiring footprint.

At 127 qubits, the Eagle processor family incorporates more scalable packaging technologies than previous generations. In particular, signals pass through multiple chip layers so as to allow for high-density I/O without sacrificing performance.

`r3` (December 2022) Eagle r3 is a version of the 127-qubit processor with enhanced coherence properties but otherwise similar design parameters to Eagle r1.

`r1` (December 2021) At the qubit level, Eagle r1 uses similar design elements and parameters to Falcon r5.11, enabling similarly fast readout. Gate speeds and error rates should also be similar.

`r1` (December 2022) The first realization of the Egret processor has demonstrated the highest Quantum Volume among IBM&reg; QPUs and a substantial improvement in two-qubit gate error rates (see [Pushing quantum performance forward with our highest Quantum Volume yet](https://www.ibm.com/quantum/blog/quantum-volume-256)). This new quantum processor boasts a substantial speedup and fidelity improvement (many gates approaching 99.9%) in two-qubit gates while reducing spectator errors.

`r5.11` (January 2021) In addition to the filtering in r5.10, design improvements target speed-ups in qubit state readout. An essential requirement for quantum error correction demonstrations is fast readout. To enable this, the paradoxical requirements of stronger readout coupling yet protection from qubit relaxation is accomplished with advanced filtering techniques and fine tuning of various components’ couplings on-chip. This revision, combined with the latest in control electronics, enables mid-circuit measurements.

`r5.10` (December 2020) This revision pioneered advanced on-chip filtering techniques that eventually led to the faster qubit state readout in r5.11. The filters reduce qubit relaxation and preserve lifetime. Additionally, space-saving “direct-couplers” are used to couple qubits together, essential for scaling to larger bird families.
103-
104-
`r4` (April 2020) Adding to the capabilities of r1, the r4 is the first revision in the large birds to deploy multiplexed readout. Previous designs required an independent signal pathway on the chip, as well as in the dilution refrigerator and control electronics for qubit state readout.
105-
106-
`r1` (February 2020) The first generation of the Falcon family, r1 is a 28Q offering independent readout, contrasting to the multiplexed configurations in the other revisions. The flip-chip technology allowed scaling to a larger number of qubits. The heavy-hex connectivity graph is employed for the first time here, optimal for our two-qubit gate of choice, cross-resonance.
