-The most visible issue is the X readout fidelity, which can be witnessed when measuring SPAM fidelity with a "Prepare $\ket{+}$ - Measure $X$" sequence. Our transmon-free X readout technique was introduced in [our recent Nature paper](https://arxiv.org/abs/2307.06617), as a first of its kind. It enabled us to reach very long bit-flip lifetimes, but it still lacks optimization. We must however optimize it so it can be used in a phase-flip QEC scheme. This is why:

 - We are currently developing new transmon-free readout techniques that will enable us to reach below threshold operation.
 - We may open pulse-level access to a Boson 4 chip to accelerate the discovery of new techniques. [Let us know](../contact_us.md) if you are interested in a collaboration.

 💡 **Note:** if you're used to working with transmons, you know that state decay only happens if you start from the $\ket{1}$ state. With cat qubits, the $\ket{0}$ and $\ket{1}$ states are virtually interchangeable. Experimental differences might remain, but they're mostly due to sampling noise and calibration inaccuracies.

Furthermore, since we are only concerned in the two pointer states $\left|0\right\rangle$ and $\left|1\right\rangle$, the distinction between the two can be enhanced using thresholding.
