We introduce the problem of constructing weighted complex projective 2-designs from the union of a family of orthonormal bases. If the weight remains constant across elements of the same basis, then such designs can be interpreted as generalizations of complete sets of mutually unbiased bases, being equivalent whenever the design is composed of d+1 bases in dimension d. We show that, for the purpose of quantum state determination, these designs specify an optimal collection of orthogonal… 
Mutually Unbiased Product Bases
A pair of orthonormal bases are mutually unbiased (MU) if the inner products across all their elements have equal magnitude. In quantum mechanics, these bases represent observables that are

Mutually unbiased bases (MUBs) are important in quantum information theory. While constructions of complete sets of d + 1 MUBs in Copfd are known when d is a prime power, it is unknown if such
Weak mutually unbiased bases
Quantum systems with variables in are considered. The properties of lines in the phase space of these systems are studied. Weak mutually unbiased bases in these systems are defined as bases for which
Mutually orthogonal Latin squares from the inner products of vectors in mutually unbiased bases
Mutually unbiased bases (MUBs) are important in quantum information theory. While constructions of complete sets of d + 1 MUBs in C-d are known when d is a prime power, it is unknown if such complete
Mutually orthogonal Latin squares and mutually unbiased bases in dimensions of odd prime power
A simple algebraic construction of MOLS is given from two known constructions of MUBs in the odd prime power case.
Tomographically complete sets of orthonormal bases in finite systems
Quantum systems where the position and momentum are in the ring (d is an odd integer) are considered. A tomographically complete set of bases, i.e. a set of bases such that probabilities from
Quantum Conical Designs
Complex projective t-designs, particularly SICs and full sets of MUBs, play an important role in quantum information. We introduce a generalization which we call conical t-designs. They include
The Curious Nonexistence of Gaussian 2-Designs
Ensembles of pure quantum states whose 2nd moments equal those of the unitarily uniform Haar ensemble—2-designs—are optimal solutions for several tasks in quantum information science, especially
Quantum Measurements in the Light of Quantum State Estimation
Starting from a simple estimation problem, here we propose a general approach for decoding quantum measurements from the perspective of information extraction. By virtue of the estimation fidelities
Symplectic spreads, planar functions, and mutually unbiased bases
By using the new notion of pseudo-planar functions over fields of characteristic two, new explicit constructions of complete sets of MUBs and orthogonal decompositions of special Lie algebras are given.


Mutually unbiased bases are complex projective 2-designs
It is demonstrated that maximal sets of MUBs come with a rich combinatorial structure by showing that they actually are the same objects as the complex projective 2-designs with angle set {0, 1/d}.
Constructions of Mutually Unbiased Bases
This work gives a simplified proof of this fact based on the estimation of exponential sums that extremal sets containing d+1 mutually unbiased bases are known to exist.
New construction of mutually unbiased bases in square dimensions
The construction combines the design-theoretic objects (s, k)-nets and generalized Hadamard matrices of size s to show that k = w + 2 mutually unbiased bases can be constructed in any square dimension d = s2 provided that there are w mutually orthogonal Latin squares of order s.
There is no generalization of known formulas for mutually unbiased bases
In a quantum system having a finite number N of orthogonal states, two orthonormal bases {ai} and {bj} are called mutually unbiased if all inner products ⟨ai∣bj⟩ have the same modulus 1∕N. This
The limitations of nice mutually unbiased bases
It is shown that the number of resulting mutually unbiased bases can be at most one plus the smallest prime power contained in the dimension, and therefore that this construction cannot improve upon previous approaches.
Tight informationally complete quantum measurements
We introduce a class of informationally complete positive-operator-valued measures which are, in analogy with a tight frame, 'as close as possible' to orthonormal bases for the space of quantum

Evenly distributed unitaries: On the structure of unitary designs
We clarify the mathematical structure underlying unitary t-designs. These are sets of unitary matrices, evenly distributed in the sense that the average of any tth order polynomial over the design
Mutually unbiased bases and orthogonal decompositions of Lie algebras
Monomial MUBs are defined, a class of which all known MUB constructions are members, and it is shown that for n = 6 there are at most three monomial Mubs.
