Whence Deep Realism for Everettian Quantum Mechanics?
‘Shallow’ and ‘deep’ versions of scientific realism may be distinguished as follows: the shallow realist is satisfied with belief in the existence of...
-
Can Pragmatist Quantum Realism Explain Protective Measurements?
According to Healey’s pragmatist quantum realism, the only physical properties of quantum systems are those to which the Born rule assigns...
-
Perspectival Quantum Realism
The theories of pre-quantum physics are standardly seen as representing physical systems and their properties. Quantum mechanics in its standard form...

Experimental assessment of physical realism in a quantum-controlled device
Bohr’s complementarity principle has been challenged by quantum delayed-choice experiments wherein quantum systems are claimed to behave neither as...

Anonymous quantum conference key agreement using the W state
Anonymous conference key agreement (ACKA), also known as multiparty key distribution, is a cryptographic task in which multiple parties hope to...
-
Completely Discretized, Finite Quantum Mechanics
I propose a version of quantum mechanics featuring a discrete and finite number of states that is plausibly a model of the real world. The model is...

Insights into Quantum Contextuality and Bell Nonclassicality: a Study on Random Pure Two-Qubit Systems
We explore the relationship between Kochen-Specker quantum contextuality and Bell-nonclassicality for ensembles of two-qubit pure states. We present...

Phenomenology, Perspectivalism and (Quantum) Physics
It has been claimed that Massimi’s recent perspectival approach to science sits in tension with a realist stance. I shall argue that this tension can...

The Wentaculus: Density Matrix Realism Meets the Arrow of Time
In this paper, I characterize and elaborate on the “Wentaculus” theory, a new approach to time’s arrow in a quantum universe that offers a unified...

t is not time: reality, causality, and the arrow of events in quantum theory
The starting point of this article is the uncircumventable interference of observational instruments in our observations of nature in quantum physics...

On the Strangeness of Quantum Mechanics
The extravagances of quantum mechanics (QM) never fail to enrich daily the debate around natural philosophy. Entanglement, non-locality, collapse,...

Ontology and the foundations of quantum theory
A brief review of the historical main line of investigation of the ontology of quantum theory is given with an emphasis on elementary particles....

Quantum Paradoxes
The famous Schrödinger’s cat paradoxSchrödinger’s cat and its variant, the Wigner’s friend paradoxWigner’s friend paradox, are discussed. These...

9 Quantum Operations on Qubitsand Their Characterization
Information encoded in quantum system has to obey rules of quantum physics which impose strict bounds on state estimation and on possible...

What Ontology for Relational Quantum Mechanics?
In this paper, we evaluate some proposals that have been put forward to clarify the ontological consequences of relational quantum mechanics. We...

Complementarity relations of a delayed-choice quantum eraser in a quantum circuit
We propose a quantum circuit that implements a delayed-choice quantum eraser via bipartite entanglement with the extension that the degree of...
-
Quantum Bits, Entanglement and Applications
In this chapter, we deal with a general introduction to quantum computation and describe the bipartite entanglement of pure and mixed states. We also...

5 Unknown Quantum States and Operations,a Bayesian View
The classical de Finetti theorem provides an operational definition of the concept of an unknown probability in Bayesian probability theory, where...

Optical Quantum Computing
Since the shift from the passive observation to the active manipulation of quanta (photons, electrons, atoms, molecules, etc.) in the 1980s and...
