Q1.
In the context of quantum error correction, consider the [[7,1,3]] Steane code. Which of the
following accurately describes the relationship between the code's stabilizer generators
and its logical operators?
A. The logical X and Z operators commute B. The logical X and Z operators are
with all stabilizer generators but are not themselves stabilizer generators and thus
themselves stabilizer elements. commute with each other.
C. The stabilizer generators are chosen to D. The logical operators must commute with
anti-commute with logical operators to each other and anti-commute with stabilizer
enable fault-tolerant measurement. generators to allow error detection.
Correct: A - The logical X and Z operators commute with all stabilizer generators but are
not themselves stabilizer elements.
Rationale:In the Steane code, logical operators are in the centralizer of the stabilizer group
but not in the stabilizer itself, ensuring they commute with all stabilizers but are not products
of them. Option B is false because logical operators are not stabilizers. Option C is false
because stabilizers commute with logicals. Option D is false because logical X and Z
anti-commute with each other, not with stabilizers.
Q2.
Consider a continuous-time Markov chain with generator matrix Q. Which condition is
necessary and sufficient for the chain to have a unique stationary distribution?
A. The chain is irreducible and all states are B. The chain is aperiodic and all states are
positive recurrent. transient.
C. The generator matrix Q has an D. The chain is irreducible and the sum of
eigenvalue equal to zero with multiplicity the rates out of each state is finite.
one.
Correct: A - The chain is irreducible and all states are positive recurrent.
Rationale:For continuous-time Markov chains, irreducibility and positive recurrence are
necessary and sufficient for a unique stationary distribution. Option B is incorrect because
transient states imply no stationary distribution. Option C is necessary but not sufficient
without irreducibility. Option D is insufficient because irreducibility is also required.

Q3.
Evaluate the improper integral ^ x³ e^{-x²} dx. Which of the following is the correct value?
A. 1/2 B. 1
C. /4 D. 1/4
Correct: A - 1/2
Rationale:Substitute u = x², du = 2x dx, then x³ dx = (1/2)u du, so integral becomes
(1/2)^ u e^{-u} du = (1/2)(2) = 1/2. Options B, C, and D are incorrect values.
Q4.
In econometrics, when using instrumental variables, which condition is required for the
instrument to be valid?
A. The instrument is correlated with the B. The instrument is uncorrelated with the
endogenous regressor and uncorrelated endogenous regressor but correlated with
with the error term. the outcome.
C. The instrument is correlated with the D. The instrument is exogenous and has no
error term but uncorrelated with the correlation with the endogenous regressor.
regressor.
Correct: A - The instrument is correlated with the endogenous regressor and uncorrelated
with the error term.
Rationale:A valid instrument must satisfy relevance (correlated with the endogenous
variable) and exogeneity (uncorrelated with the error term). Option B is wrong because it
needs correlation with the regressor. Option C is wrong because correlation with error violates
exogeneity. Option D is wrong because no correlation with regressor violates relevance.
Q5.
Which of the following problems is NP-complete in the general case but solvable in
polynomial time for planar graphs?
A. Vertex Cover B. Hamiltonian Cycle
C. Graph Isomorphism D. 3-SAT
Correct: A - Vertex Cover
Rationale:Vertex Cover is NP-complete in general but has polynomial-time algorithms on
planar graphs. Hamiltonian Cycle remains NP-complete on planar graphs. Graph
Isomorphism is not known to be NP-complete. 3-SAT is NP-complete and not restricted to
planar graphs in the same way.
