“Classifying Quantum Entanglement
using the Local Unitary Group Action”
Abstract: Non-relativistic
quantum mechanics asserts the existence of
entangled
quantum states, that is multi-particle states for which
individual
particles cannot be given well-defined states.
Such
entangled
states are ubiquitous; they form a dense subset of the
space of
composite quantum states. An important
problem is to
understand
which types of entanglement are the same and which are
different. We address this problem for systems of n
quantum bits
(qubits) by studying the action of the local unitary
group SU(2)^n
on the
space of quantum states CP^(2^n-1). This
talk will give some
physical
background to motivate the problem, then discuss the orbits
and orbit
space for two and three qubits. A general result for n
qubits will also be mentioned.
