Future Architectures Flashcards
What did IBM do that was so impressive?
They manipulated single atom on to the images spelling out their logo on a copper surface, each dot was one atom
Electricity in copper is slower or faster?
Slower than photon speed
What do photons need to interact with each other?
Electro-optical hybrids but that slow down the speed
What is an optical correlator?
Special cases of the optical system used for a single purpose, it’s used for deep learning thanks to transforming calculations
What does a filter do?
Reads the data but it has slow convolution but becomes first multiplication
What company commercialise optical correlators and who invented it?
Optalysys LTD and Dr Nick New
In simple terms explain what DNA produces…
DNA makes RNA, which RNA makes protein (base 4 encoding, alphabet-alike)
What’s quantum architecture?
Objects do not just exist in a single state, they exist in a set of states each with a probability
What does observation do?
It changes the state
What’s decide in quantum?
Which state they are in according to the probabilities and the others go away for ever
What’s representation in quantum?
When the object exists in a superposition of states each with a complex number amplitude
What’s processing in quantum?
Physical action is done to the system apart from observation are unitary matrix operators on the state vector
What’s Grover’s Algorithm?
Performs a search over ‘N’ items in ‘O’ (squared N) time.
What’s a difference between transistor and ion channel?
Lowest level components from chemistry and quantum mechanics
What is the macro architecture?
It’s like a computer but with its memory compared to the brain impulses and nerves
What’s a microcircuit?
A simple machine made of several compute units, repeated in many places
What’s a cortical pathway?
Hierarchical stages such as like detect edge, corner, face or an object
What’s the meaning of consciousness?
No real answer, it’s all matter of discussion it can have two different meanings: unitary and coherent
What’s the hippocampus and where is it?
A part of the brain, special part of the cortex, top of the structure which is modified from the rest
What’s a standard model in physics?
The theory describing three of the four known fundamental forces
What did Gödel do or say?
That time-travel is consistent with Einstein’s relativity, you can see the future by looking at the past
What’s a warp drive?
Faster than light travel from A to B it is achieved by wrapping spacetime in front and behind like aeroplane wing (like aerodynamics kinda not alike)
