Geometry of Quantum States

- I. Bengtsson, K. Życzkowski
- Physics
- 1 December 2007

a ) p. 131 The discussion between eqs. (5.14) and (5.15) is incorrect (dA should be made as large as possible!). b ) p. 256 In the figure, the numbers 6) and 7) occur twice. c ) p. 292 At the end of… Expand

ON MUTUALLY UNBIASED BASES

- T. Durt, B. Englert, I. Bengtsson, K. Życzkowski
- Mathematics
- 20 April 2010

Mutually unbiased bases for quantum degrees of freedom are central to all theoretical investigations and practical exploitations of complementary properties. Much is known about mutually unbiased… Expand

Black Holes and Wormholes in 2+1 Dimensions

- Stefan Åminneborg, I. Bengtsson, D. Brill, S. Holst, Peter Peldán
- Physics
- 15 July 1997

Vacuum Einstein theory in three spacetime dimensions is locally trivial, but admits many solutions that are globally different, particularly if there is a negative cosmological constant. The… Expand

A spinning anti-de Sitter wormhole

- Stefan Åminneborg, I. Bengtsson, Soren Holst Norra Reals gymnasium, Stockholm, Fysikum, S. University
- Mathematics, Physics
- 8 May 1998

We construct a (2 + 1)-dimensional spacetime of constant curvature whose spatial topology is that of a torus with one asymptotic region attached. It is also a black hole whose event horizon spins… Expand

Mutually unbiased bases and Hadamard matrices of order six

- I. Bengtsson, W. Bruzda, Åsa Ericsson, Jan-Åke Larsson, W. Tadej, K. Życzkowski
- Mathematics
- 22 May 2007

We report on a search for mutually unbiased bases (MUBs) in six dimensions. We find only triplets of MUBs, and thus do not come close to the theoretical upper bound 7. However, we point out that the… Expand
