Given the state of a two-qubit system as (1/2 + i/2) |00⟩ + (1/2) |01⟩ – (i/2) |11⟩, we can calculate the probability of observing the state |01⟩. To do this, we need to understand the principles of quantum superposition and the measurement process. In quantum mechanics, a qubit is the fundamental unit of quantum

The uncertainty principle, a fundamental concept in quantum information, establishes a limit on the precision with which certain pairs of physical properties of a quantum state, such as position and momentum or energy and time, can be simultaneously known. This principle, first formulated by Werner Heisenberg in 1927, has profound implications for our understanding of
