Give the circuit for the 2-qubit Inverse Quantum Fourier Transform utilizing just entryways from the set {H, CT, CNOT}, where CT is a controlled T door. [4 marks] 15 CST2.2021.9.16 15 Types (a) In an essentially composed lambda analytics increased with top of the line continuations, booleans, a rundown nd its iterator (i.e., crease, yet not full recursion), work each : (X → Bool) → List X → Bool to such an extent that each p xs returns valid assuming each component of xs fulfills p, and bogus in any case. This capacity ought to likewise quit repeating over the rundown when it tracks down a bogus component. You might utilize SML-or OCaml-style documentation whenever wanted, however make sense of any documentation utilized past the fundamental lambda analytics. [4 marks] (b) In the monadic lambda math with state, assume we change the composing rule for perusing areas to not cause a monadic impact: If we propose changing the monadic lambda analytics to allow regarding peruses as unadulterated: l : X ∈ Σ Σ; Γ ' !l : X (I) Is this standard still typesafe? Casually yet cautiously legitimize your response. [2 marks] (ii) Is the accompanying normal subexpression disposal change sound? Either give a contention why it is, or supply a counterexample and make sense of why it shows it isn't.
