## Limericks

(This limerick is joint work with Mark M. Wilde)

Why are some qubits still crap?

Quantum superpositions, the noise tries to scrap

A fine discovery

is Petz recovery

Which approximately reverses a noise map.

The Petz map and the measurement called 'pretty good'

Are mathematical constructs that you would

like to show off in experiment

to delight and all merriment

And now we can say just how you should. :)

Petz recovery does a pretty good job

When Alice sends noisy qubits to Bob

But how to perform?

With quantum singular value transform

It's as simple as that, no prob.

### Robust Quantum Minimum Finding [arXiv]

An age-old problem with a twist;

Find the minimum of a list.

When the comparator is rough

Is Durr-Hoyer enough --

Could a quantum speedup still exist?

We answer this question with a 'yes'.

Counting pivots saves us from a mess.

Hypothesis selection

Is a promising direction

When we use a ScheffĂ© test!
