but our view at the time in twenty

but our view at the time in twenty fourteen was that we were looking

fourteen was that we were looking

fourteen was that we were looking forward and we thought that in ten years

forward and we thought that in ten years

forward and we thought that in ten years time so the mid-2020s there might be the

time so the mid-2020s there might be the

time so the mid-2020s there might be the first prototypes of quantum computing

first prototypes of quantum computing

first prototypes of quantum computing and what we wanted to do was take the

and what we wanted to do was take the

and what we wanted to do was take the tools the quantum algorithms and the

actually useful we thought that by the middle of the 2020s

middle of the 2020s

middle of the 2020s the first prototypes would be here well

the first prototypes would be here well

I spend an increasing amount of time

I spend an increasing amount of time especially in this last six months or so

especially in this last six months or so

especially in this last six months or so telling people about quantum computers

telling people about quantum computers

telling people about quantum computers and I strongly believe that you have to

and I strongly believe that you have to

and I strongly believe that you have to take the mystery out of the quantum

take the mystery out of the quantum

take the mystery out of the quantum machine and I’ll let you into the little

here in the mid 30s that there was a way to compute and allow those computations

to compute and allow those computations

to compute and allow those computations to help us and then they became these
