The proposal of spontaneous collapse of quantum states has much appeal, as it does not require a lot of metaphysical baggage.

We will consider energy extraction from quantum batteries and quantum state discrimination by using local quantum operations.

Photons exhibit many interesting quantum features, such as entanglement and bosonic indistinguishability, which contradict our classical view.

We can understand quantum theory better if we stop asking how it represents the world and ask instead how we are able to use it so successfully in predicting, explaining and controlling the world.

My first talk left out physical details of key ideas in a pragmatist sketch of quantum theory. This talk is about what needs to be done to complete the picture.

What is a local subsystem in quantum gravity? How do we define its entanglement entropy?

We consider two interacting systems when one is treated classically while the other remains quantum. Despite several famous no-go arguments, consistent dynamics of this coupling exist, and we derive its most general form.
