Everything interacts with everything else. For a simple molecule, the equation doesn’t look like this … … it looks like this. #IBMQ #ibmcloudgarage @holly_cummins

It’s not this … ….it’s this. #IBMQ #ibmcloudgarage @holly_cummins

we all know from software development, handling big problems is hard unless … … we can break them down into small problems

The best supercomputer in the world can accurately simulate a 40-50 electron system. #IBMQ #ibmcloudgarage @holly_cummins

So we approximate. #IBMQ #ibmcloudgarage @holly_cummins

How good are the approximations? #IBMQ#ibmcloudgarage #ibmcloudgarage@holly_cummins @holly_cummins #IBMQ Source: http://cccbdb.nist.gov

If nature has a lot of computational complexity, can we use it for computations?

yes (for some categories of problems)

#IBMQ #ibmcloudgarage @holly_cummins

Where’s the Queen? #IBMQ #ibmcloudgarage @holly_cummins

#IBMQ #ibmcloudgarage @holly_cummins

We can search for an answer to a problem as long as it’s quick to verify correctness. #IBMQ #ibmcloudgarage @holly_cummins

A physical state that is in a definite state can still behave randomly. #IBMQ #ibmcloudgarage @holly_cummins

A physical state that is in a definite state can still behave randomly. #IBMQ #ibmcloudgarage @holly_cummins Two systems that are too far apart to influence each other can still behave in ways that, although individually random, are still strongly correlated.

A physical state that is in a definite state can still behave randomly. Two systems that are too far apart to influence each other can still behave in ways that, although individually random, are still strongly correlated. Quantum computing is about working out how to use these two principles for a new model of computation. #IBMQ #ibmcloudgarage @holly_cummins

If you find this confusing, you should. #IBMQ #ibmcloudgarage @holly_cummins

The physicists who discovered this were totally confused. #IBMQ #ibmcloudgarage @holly_cummins

“You surely must understand that the whole idea of quantum jumps necessarily leads to nonsense.” #IBMQ Schrödinger #ibmcloudgarage Erwin @holly_cummins

“… physics should represent a reality in time and space, free from spooky actions at a distance.” “God does not play dice.” #IBMQ #ibmcloudgarage Albert Einstein #IBMQ #ibmcloudgarage @holly_cummins Photo: Bomazi
