On 22 and 23 April 2026<\/a>, the Hotel Zenith Conde Orgaz in Madrid hosted the second edition of the Introduction to Quantum Computing and Post-Quantum Cryptography Course organized by EADTrust<\/a><\/p>\n\n\n\n

During two intensive working days, a group of professionals \u2014 lawyers, economists, financial directors, compliance officers, and engineers \u2014 built a Bloch sphere with their own hands, executed real quantum circuits in IBM Composer, and understood why RSA and ECC<\/a> are living on borrowed time. This is the chronicle of what happened.<\/p>\n\n\n\n

Why does EADTrust organize a course on quantum computing?<\/h2>\n\n\n\n

The answer is straightforward: because quantum computing is not an abstract future threat. It is a threat with timelines<\/strong>, approved standards, and regulations that are already in force.<\/p>\n\n\n\n

What we call the \u201ccryptocalypse\u201d <\/strong>\u2014 the moment when a quantum computer becomes capable of breaking the asymmetric cryptography algorithms that currently protect payments, contracts, certificates, and communications \u2014 is, according to every technical and regulatory indicator, a question of when<\/em>, not if<\/em>.<\/p>\n\n\n\n

NIST<\/a> has already published the first post-quantum cryptography standards. ENISA<\/a> is actively promoting adoption initiatives. Spain\u2019s CCN<\/a> has issued guidance so that essential and critical entities can achieve a state of Quantum Readiness<\/em>. And organizations such as ETSI are actively working on standardization.<\/p>\n\n\n\n

As a Qualified Trust Service Provider (QTSP), EADTrust has the responsibility to bring this technical and regulatory reality to the teams that need to make decisions now. That is the origin of this course.<\/p>\n\n\n\n

The International Year of Quantum Science and Technology<\/h2>\n\n\n\n

This second edition arrives at a particularly relevant moment. The year 2025 was declared the International Year of Quantum Science and Technology<\/strong> by the United Nations through Resolution 78\/287, adopted on 7 June 2024<\/a>, to commemorate the centenary of quantum mechanics. The initiative was supported by nearly 300 organizations.<\/p>\n\n\n\n

At the same time, 2025 brought concrete advances: Microsoft announced the first commercial quantum computer with 24 logical qubits operating in the cloud, IBM and AMD formalized a partnership to integrate quantum computing with classical supercomputing, and Gartner projected a 9% increase in global technology investment focused on disruptive technologies such as quantum computing.<\/p>\n\n\n\n

EADTrust <\/a>had already organized the first edition of this course on 12 and 13 November 2025, marking the beginning of a series of activities that will include quantum programming workshops and methodologies for assessing the use of cryptography within organizations. The April 2026 edition consolidates that journey.<\/p>\n\n\n\n

The speakers: who was in the room<\/h2>\n\n\n\n

The course featured four speakers with complementary profiles, covering the full spectrum of the quantum challenge: from physical fundamentals to regulatory implications and market applications.<\/p>\n\n\n\n

Jorge Christen<\/strong> is a quantum computing expert with extensive international experience designing solutions for the financial industry. He is the creator of the ENSAR methodology<\/a> \u2014 the pedagogical framework structuring the entire first day \u2014 and a professor at the University of Monterrey, where he has delivered quantum computing training in Mexico, the United States, and Spain.<\/p>\n\n\n\n

Antonio Peris<\/strong> is co-founder of QCentroid<\/a>, a company specializing in quantum computing applications for sectors such as healthcare, energy, finance, and industry. His background combines computer science, marketing, and management, with a focus on building collaborative environments that accelerate quantum innovation.<\/p>\n\n\n\n

Ainhoa Inza<\/strong> is Director of Professional Services and Compliance at EADTrust. She has led the TCAB (Trust Conformity Assessment Body<\/em>), is an expert in eIDAS auditing, cybersecurity, digital identity management, cryptography, blockchain, and GRC, and holds the CISA (Certified Information Systems Auditor<\/em>) certification.<\/p>\n\n\n\n

Juli\u00e1n Inza<\/strong> is President of EADTrust and a specialist in cryptography and cybersecurity. He has collaborated with several Trust Service Providers and served as an evaluator for providers within TCAB. During the course, he led the module on international initiatives for the standardization of post-quantum algorithms and adoption strategies.<\/p>\n\n\n\n

Day 1 \u2014 From Planck to IBM Composer: building a qubit with your own hands<\/h2>\n\n\n\n

The first day, led by Jorge Christen<\/strong>, started from an unusual point for a technical course: the history of physics.<\/p>\n\n\n\n

\"Curso<\/figure>\n\n\n\n

From the predictable universe to the quantum universe<\/h3>\n\n\n\n

At the end of the nineteenth century, physics seemed almost complete. Newton\u2019s laws and Maxwell\u2019s electromagnetism described a predictable and orderly universe. But a group of visionary minds \u2014 Max Planck, Albert Einstein, Niels Bohr, Werner Heisenberg, and Erwin Schr\u00f6dinger \u2014 dared to challenge the established view. Quantum physics was born: a science where light can behave as both particle and wave at the same time, where particles may exist in several places simultaneously, and where randomness governs the core of matter.<\/p>\n\n\n\n

Jorge Christen used this historical journey not as decoration, but as a pedagogical framework. Before speaking about qubits, attendees needed to understand why quantum reality is counterintuitive \u2014 and why that matters for cryptography.<\/p>\n\n\n\n

The ENSAR methodology: when physics becomes tangible<\/h3>\n\n\n\n

The distinctive element of the first day was the application of the ENSAR methodology <\/strong>(Experience, Name, Speak, Apply and Repeat<\/em>), created by Jorge Christen himself to enable people with no prior knowledge of quantum physics to understand and operate quantum computing systems.<\/p>\n\n\n\n

The method is not theoretical. Participants worked with the IQC Kit <\/strong>(Introduction to Quantum Computing<\/em>), a set of physical materials through which they progressively built mechanical representations of highly complex concepts. Superposition, entanglement, and the Bloch sphere \u2014 concepts that appear abstract on paper \u2014 became physically manipulable in the hands of every attendee.<\/p>\n\n\n\n

The technical path of the first day covered the foundations of quantum computing (qubits, superposition, entanglement, the Bloch sphere, quantum gates, and circuits), the use of a real quantum computer through IBM\u00ae Composer<\/strong>, and a review of the current state of the art in quantum technologies and platforms. Attendees used Dirac notation and incorporated quantum gates such as the Hadamard gate into their own circuits.<\/p>\n\n\n\n

The level of feedback was exceptional. Lawyers, economists, engineers, and professionals from public administrations, banking, and insurance sectors \u2014 without a single previous hour of quantum physics training \u2014 finished the first day having executed their own circuits on a real quantum computing platform.<\/p>\n\n\n\n

Day 2 \u2014 From the quantum market to the cryptocalypse: what can no longer wait<\/h2>\n\n\n\n

The second day was denser, more regulatory, and for many attendees, the most urgent. The order was: first Antonio Peris, then Ainhoa Inza, and finally Juli\u00e1n Inza. The day ended with certificate delivery and a long conversation that was never part of the official program.<\/p>\n\n\n\n

Antonio Peris (QCentroid): what is already happening in the quantum market<\/h3>\n\n\n\n

The opening session of the second day was delivered by Antonio Peris<\/strong>, co-founder of QCentroid, who placed quantum computing within its real market dimension. Far removed from science-fiction narratives, Peris offered a practical perspective: which sectoral applications quantum computing already has, in which industries it is first taking root \u2014 healthcare, energy, finance, and industry \u2014 and why this is no longer merely a laboratory conversation but a matter of investment and strategic decision-making.<\/p>\n\n\n\n

QCentroid operates precisely in that space: applying quantum computing to sectors where computational performance has direct consequences for business outcomes.<\/p>\n\n\n\n

Ainhoa Inza: the complete technical and regulatory map<\/h3>\n\n\n\n

Ainhoa Inza<\/strong> led the module connecting the quantum threat with the technical and regulatory response. Attendees received the complete picture: from the quantum algorithms with the greatest impact on cryptography \u2014 especially Shor\u2019s algorithm, capable of factoring integers in polynomial time, and Grover\u2019s algorithm \u2014 to the first approved standards and regulations already in force.<\/p>\n\n\n\n

On the technical side, Ainhoa presented the post-quantum standards already published by National Institute of Standards and Technology (NIST):<\/p>\n\n\n\n
